The tripatriate union. Took partial inspiration from the Kannauj Triangle where 3 ancient kingdoms in India faught to take control of the subcontinent. In this case, after centuries of war and consolidation by various kingdoms, three distinct entities are formed-

• The Maratha confederacy gains greater fame among various hindu factions and empires, coming to be known as hindu confederacy. The kingdoms start uniting and form loose knit unions and alliances with Marathas and manage to defeat the sultanates in deccan. The confederacy continues to war against Durrani empire, the Bengal Sultanate. It defeats the Mughals, restricts them to Delhi and manages to make them their vassal state. As Marathas attempt to consolidate more power other kingdoms start demanding further autonomy, causing them to loosen grip over the Gangetic plains. The confederacy initally becomes something more akin to HRE where the Chatrapati becomes an elected position, before succumbing to revolts. Rajput kings revolt and join hands with Sikh Empire and Bengal Sultanate and fight against Marthas, where they lose northern lands. A re-unification campaign arises from South, allowing it to become a constitutional monarchy called United Kingdoms of Dakshinapatra with languages of Marathi, Konkani, Tamil, Telugu, Oriya and Kannada as state languages. Capital city- Poona.
• Bengal sulanate takes advantage of losing influence of Mughal empire and manages to consolidate power across the lower and middle Indo Gangetic plains. After facing multi front wars from Maratha empire, Ahom empire and the consolidation campaign by the Gorkha Empire, the sultanate manages to retain power. It manages to conquer low lands of Madhesh and pushes back the Gorkha empire. They manage to control most of the Deob before turing east and attacking the Ahom Empire. Sultanate forms alliance with Burmese Kingdom and manages to crush most of Ahom Empire and split the North eastern dominions between them. Manipur remains independent but becomes a vassal state. As Burmese Kingom faces attacks from Thai and Qing dynasty, they further expand into their former alliy's territory and conquer Chin state. They finally finish their conquest by surrounding and subsuming Kingdom of Manipur. The Monarchy later gives up its power to various lords and rajas before becoming a Constitutional Monarchy. Languages- Bengali, Maithili, Bhojpuri, Urdu, Assamese and Metei Capital- Murshidabad.
• Sikh Empire pushes back Durrani Empire and launches a campaign to conquer the Himalyan states. They manage to push back Gorkha expansion from eastern front and Tibetan kingdom expansion from North. They attempt to consolidate further power but get defeated by Durrani-Kalat alliance to the west. Empire takes advantage of political instability within the Maratha Confederacy, make alliances with Rajput Kings and take lands west of Aravalis and gain access to the sea with conquest of Sindh and Kutch. Empire then captures Delhi and makes Mughals their subject before attempting to fight a two front war with Dakshinpatra and Bengal Sultanate. The combined offensive pushbacks the Sikh Empire from Upper Gangetic plains. The empire's influence causes the spread of Sikhism, with the religion becoming more popular among nobility and royalty and land owning farmers. The Sikh kings are given greater autonomy, leading to further spread of religion. The kingdom starts having elected kings. Languages- Punjabi, Sindhi, Marwari, Pahari, Dogri and Kashmiri. Capital- Lahore
• The Delhi region changes hands multiple times between the three political entities leading to extensive death and destruction. Soon the three kingdoms reach a compromise and declare Delhi neutral grounds to settle differences. A political union was created and the Kingdoms started using common currency and started using Persian as a lingua franca to communicate with each other and conduct business. Open borders were allowed and a politcial confederate union called "Bharatiya Sanghrajya"/"Etehad-E-Hindustan"/ Indian Confederacy was declared.
