The people drawn from these diverse origins have coexisted peacefully for the most part. Slave revolts, such as the one in 1763 led by Guyana's national hero, Cuffy, demonstrated the desire for basic rights but also a willingness to compromise. Politically inspired racial disturbances between Indo-Guyanese and Afro-Guyanese erupted in 1962-64, and again following elections in 1997 and 2001. The basically conservative and cooperative nature of Guyanese society has usually contributed to a cooling of racial tensions. Racial tensions, however, do constitute Guyanaís greatest ongoing social stress point.

Guyanese politics, nevertheless, occasionally has been turbulent. The first modern political party in Guyana was the People's Progressive Party (PPP), established on January 1, 1950, with Forbes Burnham, a British-educated Afro-Guyanese, as chairman; Dr. Cheddi Jagan, a U.S.-educated Indo-Guyanese, as second vice chairman; and his American-born wife, Janet Jagan, as secretary general. The PPP won 18 out of 24 seats in the first popular elections permitted by the colonial government in 1953, and Dr. Jagan became leader of the house and minister of agriculture in the colonial government. Five months later, on October 9, 1953, the British suspended the constitution and landed troops because, they said, the Jagans and the PPP were planning to make Guyana a communist state. These events led to a split in the PPP, in which Burnham broke away and founded what eventually became the People's National Congress (PNC).

Elections were permitted again in 1957 and 1961, and Cheddi Jagan's PPP ticket won on both occasions, with 48% of the vote in 1957 and 43% in 1961. Cheddi Jagan became the first premier of British Guiana, a position he held for 7 years. At a constitutional conference in London in 1963, the U.K. Government agreed to grant independence to the colony but only after another election in which proportional representation would be introduced for the first time. It was widely believed that this system would reduce the number of seats won by the PPP and prevent it from obtaining a clear majority in Parliament. The December 1964 elections gave the PPP 46%, the PNC 41%, and the United Force (TUF), a conservative party, 12%. TUF threw its votes in the legislature to Forbes Burnham, who became prime minister.

Guyana achieved independence in May 1966, and became a republic on February 23, 1970--the anniversary of the Cuffy slave rebellion. From December 1964 until his death in August 1985, Forbes Burnham ruled Guyana in an increasingly autocratic manner, first as prime minister and later, after the adoption of a new constitution in 1980, as executive president. During that time- frame, elections were viewed in Guyana and abroad as fraudulent. Human rights and civil liberties were suppressed, and two major political assassinations occurred: the Jesuit Priest and journalist Bernard Darke in July 1979, and the distinguished historian and WPA Party leader Walter Rodney in June 1980. Agents of President Burnham are widely believed to have been responsible for both deaths.

Following Burnham's own death in 1985, Prime Minister Hugh Desmond Hoyte acceded to the presidency and was formally elected in the December 1985 national elections. Hoyte gradually reversed Burnham's policies, moving from state socialism and one-party control to a market economy and unrestricted freedom of the press and assembly. On October 5, 1992, a new National Assembly and regional councils were elected in the first Guyanese election since 1964 to be internationally recognized as free and fair. Cheddi Jagan was elected and sworn in as president on October 9, 1992.

When President Jagan died in March 1997, Prime Minister Samuel Hinds replaced him in accordance with constitutional provisions. President Jagan's widow, Janet Jagan, was elected president in December 1997. She resigned in August 1999 due to ill health and was succeeded by Finance Minister Bharrat Jagdeo, who had been named prime minister a day earlier. National elections were held on March 19, 2001. Incumbent President Jagdeo won reelection with a voter turnout of over 90%.
