Tej Singh

Tej Singh (1799 – 4 December 1862; or Raja Teja Singh) was a Sikh commander in the Sikh Empire. He was appointed as commander-in-chief of the Sikh Khalsa Army during the First Anglo-Sikh War betraying the army he was supposed to lead.

In return for his loyalty to the invader, the East India Company, made Tej Singh Raja of Sialkot. It appointed him to head the Council of Regency on behalf of the minor Duleep Singh. He was one of six signatories to the 1849 Treaty of Lahore, which agreed to the surrender of the Koh-i-Noor diamond by the Maharaja of Lahore to the Queen of England. All the signatories, on behalf of the minor Duleep Singh, endorsed the treaty in return for being permitted to retain their jagirs. Provided by Wikipedia
