The general strike of 1902 (French: grève générale de 1902, Dutch: algemene staking van 1902) was a major general strike in Belgium, aimed at forcing electoral reform and notably the end of the system of plural voting. It officially lasted between 10 and 20 April. The 1902 strike was the second general strike in Belgium's history and although the largest, it was ultimately unsuccessful at achieving its objectives.
The 1902 strike followed the general strike of 1893 which had led to the creation of universal male suffrage, moderated by plural voting. The resulting system gave disproportional political power to the rich. Nevertheless, Emile Vandervelde and the leadership of the Belgian Workers' Party (POB-BWP), as well as the trade unions, were reluctant to take further action. The general strike of 1902 was therefore forced by coal miners in Wallonia who were angry at their poor living conditions. It was also supported by anarchists who believed that a general strike could become a full-fledged revolution.
Wildcat strikes broke out among miners in the Province of Liège on 8 April 1902. Fearing that the party were losing control, the POB-BWP declared an official general strike on 10 April. From the start, the strike was particularly violent. In one incident, six strikers were killed by police in Leuven. In total, 12 workers and one policeman were killed. However, parliament refused to reopen the subject of voting reform. On 20 April, the POB-BWP declared the strike ended and most of the strikers returned to work the following morning.
