Brazil gained its independence on September 7th, 1822, when Dom Pedro proclaimed Brazil's independence after an antagonistic relationship with Portugal proved too much for the Brazilian people. It all began when Napoleon I invaded Portugal in 1807.
Hi my dear friend,
The First Battle of Panipat was fought between the invading forces of Babur and the Lodi Empire, which took place on 21 April 1526 in North India. It marked the beginning of the Mughal Empire. This was one of the earliest battles involving gunpowderfirearms and field artillery.
