Chile (1810.9.18-1814.10.2; 1818.1.12- )

1. Government of the Republic (1810.9.18-1814.10.2; 1818.1.12- )

In 1810 revolution broke out in Chile and the revolutionaries established this regime, which was crushed by Spain in 1814. In 1818 Chile declared independence from Spain again. Between 1823 and 1891 Chile was basically ruled by the Liberal Party and the Conservative Party alternately. From 1891 onwards real power was held by the Congress dominated by the Conservatives. In 1925 the President resumed power. After Pinochet staged a coup in 1973, Chile came under dictatorial rule until 1990, when civilian rule was restored. But Pinochet continued to hold the military power until 1998. Thereafter democracy was gradually restored in Chile.

Provincia Oriental del Rio de la Plata-Montevideo-Uruguay (1825.8.25- )

In 1825 Provincia Oriental del Rio de la Plata declared independence from Brazil and joined the United Provinces of the Rio de la Plata. In 1828 this province seceded from Rio de la Plata and established the State of Montevideo, which was renamed Uruguay in 1830. Between 1830 and 1868 Uruguay was under the alternate rule of the National Party and the Colorado Party. But the political situation was unstable. Between 1868 and 1952 the Colorado Party was in power. After a self-coup initiated by President Terra in 1933, dictatorial rule was established. Democracy was restored in 1938. In 1952 the Presidency was replaced by a National Council of Government in which the Colorado Party and the National Party shared power. But the country reverted to the presidential system in 1967. Democracy was once again suspended after a military coup in 1976. Democracy was restored in 1985 and Uruguay was again under the alternate rule of the Colorado Party and the National Party between 1985 and 2005.
