From its inception, the Progressive League was plagued by internal conflict between Progressives (former Moderate Conservatives) and Historicals (former Liberals).[84] All of the cabinets formed by the League after 1862 were short-lived. The Paraguayan invasion in 1864 led to a conflict far longer than expected, increasing tensions within the party. By 1868, a rift had opened between the Marquis of Caxias (then Commander-in-Chief of Brazilian forces in the war) and the Progressive Cabinet.
