Mir Jafar, a traitor & the beginning of British rule in India

Since time immemorial with respect to wars and expansion of empires, governance, etc there have been many acts of betrayal, back stabbing and treason carried out by certain band of daring people driven by greed, revenge and   their motives may range from the altruistic to totally selfish like betraying their own countries in return for personal gains unlike squealer or whistle blowers,  who are mainly concerned with social causes like corruption, malpractices, etc. 
The British imperialists were good at exploiting this human frailty. Mir Jafar was a close relative and military commander under the Nawob of  Bengal Siraj-ud Dalah. Robert Clive of the British India took over the control of Bengal after the Battle of Plassey – 1757; he defeated and deposed the Nawob with the help of Mir Jafar who was later made the the puppet Nawob of Bengal. As part of the deal Robert Clive took control of the Bengal army and the East India company and received large bribes from the new Nawob.

Upon realizing the British company's ambitious plan of expanding their activities all over India and his glaring mistake, the Nawob aligned with the Danish to stop them but this resulted in defeat and his exit. With tactics later he won the confidence of the British and regained the throne for which he had to pay annually a large sum to the company. He ruled the state until his death in 1765.

After his death the British took complete control over Bengal and kept it till its independence 200 years later. Because of betrayal of his own country and people, Mir Jafer indirectly helped the British lay a strong foundation on the Indian soil. The British grabbed the Indian subcontinent one by one using tactics and military power. India was a big catch, the most important country in the British Empire. Mir Jafar is still known as Gaddar-e-Abrar, the betrayer of true faith.
