In 1927, the British Government appointed a Commission. Its chairman was Sir John Simon. So, this Commission is known as Simon Commission. This Commission reached India in 1928. There was no Indian member in this Commission. Therefore, wherever this Commission went, it was greeted with black flags. Slogans of ‘Simon Commission go back’ were raised at many places. These peaceful demonstrations were suppressed by the Government cruelly. Lala Lajpat Rai was beaten with lathis at Lahore. He died of the injuries received by him a few days later. All the political parties condemned this policy of the Government.
