1757 The Battle of Plasi marked the beginning of the British conquest of India. Prasi is a place name in Bangladesh. The battle was between the army of the East India Company and the army of the Bengal maharaja. In fact, it was also the first official contest between British colonists and India. The cause of this battle was that the East India Company built a colonial city in Bangladesh, Kolkata, and extorted money in this area. In addition to collecting huge tribute, more than 100 trading posts and more than 10 British agent shops were set up to engage in trade and plunder activities. This aroused the resistance of the Bangladeshi people. 1756 In April, Bangladeshi maharaja Silaghi sent troops to occupy British institutions, and then marched into Kolkata and occupied the area. In retaliation, the East India Company mobilized troops, and on June 23rd, 1757, there was an exchange of fire with the troops of the Bangladeshi maharaja in Prasi. Robert Robert Clive was in command of the British army. He used bribery to win over the local aristocrats and Silaghi, the great monarch, to divide and disintegrate Silaghi's army, and defeated 50,000 princes with only 3,000 troops. After the defeat, Silaghi was executed, and Robert Clay established a puppet regime. From then on, the British actually became the rulers of the rich Bangladesh, and prepared for further invasion and control of the entire Indian territory.
