1910–1926
The First Republic
Republicans overthrew the monarchy on 5 October 1910, and the Constitution of 1911 gave power to a parliament that elected the president. The new regime lived through deep political, social and economic instability. Portugal entered the First World War in March 1916 and sent troops to France, and a military coup on 28 May 1926 dissolved parliament and ended the Republic.
