• From 1337 the conflict between the officers in Deccan and Delhi sultanate accelerated which led to the establishment of an independent state in the Deccan in 1347 with the capital at Gulbarga in Andhra Pradesh.
• Its founders Haran Gangu assumed the title AlauddinHasanBahman Shah as he traced his descent from the mythical hero of Iran, Bahman Shah and the kingdom was named after him, the Bahamani Sultanate.
• After Mohammad bin Tughlaq there were no attempts by the Delhi Sultanate to control the Deccan region, therefore, the Bahamani Sultans without any checks annexed the kingdom.
• There were a total of fourteen Sultans ruling over this kingdom. Among them, AlauddinBahman Shah, Muhammad Shah I and Firoz Shah were important.
• Ahmad Wali Shah shifted the capital from Gulbarga to Bidar.
• The power of the Bahmani kingdom reached its peak under the rule of Muhammad Shah III. It extended from the Arabian sea to the Bay of Bengal. On the west it extended from Goa to Bombay. On the east, it extended from Kakinada to the mouth of the river Krishna.
• The success of Muhammad Shah was due to the advice and services of his minister Mahmud Gawan.
• One of the important acquisitions was the control over Dabhol, an important port on the west coast.
• Under Bahman Shah and his son Muhammmad Shah, the administrative system was well organised.
• The kingdom was divided into four administrative units called ‘taraf’ or provinces. These provinces were Daultabad, Bidar, Berar and Gulbarga.
• Muhammad I defeated the Vijayanagar kingdom and consequently Golconda was annexed to Bahamani kingdom.
• Every province was under a tarafdar who was also called a subedar.
• Some land was converted into Khalisa land from the jurisdiction of the tarafdar. Khalisa land was that piece of land which was used to run expenses of the king and the royal household.

• Nobles used to get their salary either in cash or in form of grant of land or ‘jagir’ .
• Bahamani ruler depended for military support on his amirs.

• Between both these groups there was always tension to appropriate better administrative positions and because of their feuds, the stability of the Bahamani Sultanate was affected.
• For the first time in India both Bahamani and Vijaynagar kingdoms used gunpowder in the warfare.
• The Bahamanis were already familiar with the use of firearms. They employed Turkish and Portuguese experts to train the soldiers in the latest weaponry of warfare.
Mahmud Gawan
• One of the most important personalities in the Bahamani kingdom was Mahmud Gawan. The Bahmani kingdom reached its peak under the guidance of Mahmud Gawan.
• Mahmud Gawan’s early life is obscure. He was an Iranian by birth and first reached Deccan as a trader. He was granted the title of ‘Chief of the Merchants’ or Malikut-Tujjar by the Bahamani ruler, Humayun Shah.
• The sudden death of Humayun led to the coronation of his minor son Ahmad III. A regency council was set for the administration and Mahmud Gawan was its important member.
• He was made wazir or the prime minister and was given the title of ‘Khwaju-i-Jahan.’
• The history of Bahmani kingdom after this period is actually the record of the achievements of Mahmud Gawan.
• He lived a simple life and was magnanimous. He was also a learned person. He possessed a great knowledge of mathematics.
• He made endowments to build a college at Bidar which was built in the Persian style of architecture.
• He was also a military genius. He waged successful wars against Vijayanagar, Orissa and the sea pirates on the Arabian sea.
• His conquests include Konkan, Goa and Krishna-Godavari delta and thus he expanded the Bahmani Empire through his conquests.
• Despite of being an Afaqui he was liberal and wanted a compromise between the Afaquis and the Deccanis.
• He controlled the kingdom in an efficient manner and provided it stability.
• Gawan conquered the Vijayanagar territories up to Kanchi.
• On the western coast, Goa and Dhabol were conquered. Losing these important ports was a great loss for Vijayanagar.
• Bahamani strengthened its trading relations with Iran and Iraq after gaining control over Goa and Dabhol.
• His administrative reforms were were aimed to increase the control of Sultan over the nobles and provinces.
• Gawan carried out many internal reforms and attempted to put an end to the strife in the nobility. Royal officers were appointed in each province for this purpose. Most of the forts were under the control of these officers.
• In order to curb the military power of the tarafdar, Gawan ordered that only one fort of each province was to be under the direct control of the provincial tarafdar.
• The remaining forts of the province were placed under a Qiladar or commander of the forts. The Qiladar was appointed by the central Government.
• However, soon after his death, the governors declared their independence and the Bahamani kingdom broke up.
• In the fifteenth and the sixteenth century, some amirs in Bidar, Ahmadnagar, Golconda and Bijapur and Berar established independent sultanates of their own and formed new states.
• These were the NizamShahis of Ahmadnagar, the AdilShahis of Bijapur, the QutbShahis of Golconda, and the ImadShahis of Berar and the BaridShahis of Bidar.
• They formed a league of states and strengthened them by matrimonial alliances.
• They maintained the traditional rivalry with the Vijayanagar rulers.
• Golconda and Bijapur entered into matrimonial alliances and led the Battle of Talikota against Vijayanagar.
• They finally succumbed to the Mughal armies.
Conflicts between the Vijayanagar and the Bahamani Kingdoms
• There were constant conflicts between the Vijayanagar and the Bahamani kingdoms over the control of Raichur doab which was the land between rivers Krishna and Tungabhadra.
• This area was fertile and rich in mineral resources. The famous diamond mines of Golconda were located in the eastern part of the doab region.
• The geography of both the kingdoms was such that expansion was possible only across Tungabhadra in the Deccan.
• It appears that the battles between the two were not conclusive and the status quo was maintained.
• Sometimes, Bahamani had an advantage and sometimes, Vijayanagar had an advantage. For instance, in 1504, the Bahamani managed to reconquer the Raichur doab. However, with the ascent of Krishna Deva Raya, the Bahamanis lost Raichur, Mudkal, Nalgonda and other inland towns.
• An important result of these wars was that both the powers were so involved amongst themselves that they never realized the increasing power of the Portuguese on the coast of South India.
• Besides, continuous warfare exhausted the resources of both the states and weakened them.
• The other areas of conflict were the Marathwada region and the deltaic region of Krishna-Godavari.
• Both regions had fertile areas and important ports that controlled trade to the foreign countries.
• The fertile area in the Marathwada region was the Konkan belt that also had the port of Goa which was an important region for trade and export and import especially import of horses from Iraq and Iran.
• Often, the battles between the Vijayanagar and the Bahamani states are perceived as Hindu-Muslim conflicts, but the above mentioned reasons show that the struggle was not due to any religious differences.
• Territorial and economic motives were the main causes for the war.
• Despite hostilities between the two states, there were times when they also co-operated with each other.
• Krishna Deva Raya, for example, supported some claimants to power in the Sultanates and took pride in the title “establisher of the Yavana kingdom”.
• Similarly, the Sultan of Bijapur intervened to resolve succession disputes in Vijayanagra following the death of Krishna Deva Raya.
• There were also sharing and exchange of ideas, especially in the field of art, literature and architecture.



‘Doping’ refers to an athlete’s use of prohibited drugs or methods to improve training and sporting results. Steroids are the drugs that often come to mind when we talk about doping, but doping also includes an athlete’s use of other forbidden drugs (such as stimulants, hormones, diuretics, narcotics and marijuana), use of forbidden methods (such as blood transfusions or gene doping), and even the refusal to take a drug test or an attempt to tamper with doping controls.
Prohibited substances are:
• Stimulants directly affect the central nervous system, increasing blood flow and heart rate.
• Narcotic analgesics decrease the sensation of serious injuries, allowing athletes to continue training for competition after serious injuries.
• The cannabis products include marijuana and hashish.
• Glucocorticoids are a class of corticosteroids that affect the  metabolism  of carbohydrates, fat, and proteins, and regulate glycogen and blood pressure levels.
National Anti Doping Agency (NADA) was set up as registered society under the Societies Registration Act of 1890 on November 24, 2005 with a mandate for Dope free sports in India. The primary objectives are to implement anti-doping rules as per WADA code, regulate dope control programme, to promote education and research and creating awareness about doping and its ill effects.

Net Neutrality

Net Neutrality

Net neutrality is the principle that Internet service providers and governments should treat all data on the Internet equally, not discriminating or charging differentially by user, content, site, platform, application, type of attached equipment, or mode of communication.
Net Neutrality is about:
a) No telecom-style licensing of Internet companies
b) No gateways (, Airtel OneTouch Internet, Data VAS), censorship or selection;
c) No speeding up of specific websites
d) No “zero rating” or making some sites free over others
Significance of Net Neutrality
a) Without Net Neutrality, cable and phone companies could carve the Internet into fast and slow lanes. An ISP could slow down its competitors’ content or block political opinions it disagreed with.
b) ISPs could charge extra fees to the few content companies that could afford to pay for preferential treatment — relegating everyone else to a slower tier of service. This would destroy the open Internet.
c) Net Neutrality is crucial for small business owners, startups and entrepreneurs, who rely on the open Internet to launch their businesses, create a market, advertise their products and services, and distribute products to customers.
The Department of Telecom has formed a panel headed by A K Bhargava to examine economic impact of implementation of net-neutrality principle on the sector.

Cloud Seeding

Cloud Seeding

• Natural rainfall occurs when supercooled cold water contacts particles of dust, salt or sand forming ice crystals. The ice crystals provide a nucleus (tiny solid or liquid particles, suspended in the atmosphere) around which more water droplets can attach, increasing the size of the droplet, or in colder air snow flakes. When the droplet or snow flake, becomes large enough, it falls as snow or rain.
• It is the technique of inducing rain from a cloud, usually by dropping suitable particles into clouds containing supercooled water in an attempt to cause them to dissipate, modify their structure, or alter the intensity of associated phenomena, such as wind speed or hail.
• Weather modification, commonly known as cloud seeding, is the application of scientific technology that can enhance a cloud’s ability to produce precipitation.
• Cloud seeding is the process of spreading either dry ice, or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain.
• Weather Modification, is on the forefront of scientific technology to maximize water availability worldwide.
• Application of scientific concepts and extensive scientific experimentation has proven that cloud seeding increases the amount of precipitation.
There are three cloud seeding methods: static, dynamic and hygroscopic.
• Hygroscopic cloud seeding disperses salts through flares or explosives in the lower portions of clouds. The salts grow in size as water joins with them.
• Static cloud seeding involves spreading a chemical like silver iodide into clouds. The silver iodide provides a crystal around which moisture can condense. The moisture is already present in the clouds, but silver iodide essentially makes rain clouds more effective at dispensing their water.
• Dynamic cloud seeding aims to boost vertical air currents, which encourages more water to pass through the clouds, translating into more rain. Up to 100 times more ice crystals are used in dynamic cloud seeding than in the static method.
The process is considered more complex than static clouding seeding because it depends on a sequence of events working properly.
