The history of Guinea-Bissau's government is important to know before diving into the current events about their upcoming parliamentary elections. Guinea-Bissau was originally a Portugese colony that gained independence from them in 1974. The country has never really had prolonged political stability with military coups since becoming autonomous. During the presidental elections in July 2005, VIEIRA was elected on a second ballot over his top competitor SANHA. The legislative branch of Guinea-Bissau is the unicameral National People's Assembly. This congress consisted of several different parties and elections are held for it every four years. The party that won most of the seats back in the 2004 elections was the PAIGC with slightly over 31% of the vote. However, this branch was dismissed by the president because they failed to form a coalition with the other parties.
