Context paragraphs:
January 2001 El Salvador earthquake: The January 2001 El Salvador earthquake struck El Salvador on January 13, 2001 at 17:33:34 UTC.  The 7.6 (later estimated to be 7.7 or 7.9) quake struck with the epicenter 60 miles (100 km) SW of San Miguel, El Salvador (13.04°N 88.66°W) at a depth of 60 km.  At least 944 people were killed, 5,565 injured, 108,261 houses destroyed — with another 169,692 houses damaged — and more than 150,000 buildings were damaged in El Salvador.  About 585 of the deaths were caused by large landslides in Santa Tecla and Comasagua.  As is often the case after earthquakes in El Salvador, landslides wreaked significant damage.  Estimation of the number of slides is difficult because individual scarps conjoin.  The total has been reported as high as 16,000, though it is unclear how this figure was arrived at.  Damage and injuries occurred in every department of El Salvador, particularly the departments of La Libertad and Usulután.  Eight people were killed in Guatemala.  The tremor was felt from Mexico City to Colombia.  An aftershock measuring 5.7 magnitude was felt on January 15, an event not widely reported outside the country until after the February quake, which initially was assessed by the USGS at 5.7 magnitude as well.

American Populist Party: The American Populist Party, founded in 2009, is a minor political party which claims to advocate "classical liberalism" and a return to what they call "genuine" Constitutional government.  As such it is an amalgam of classical liberalism and modern conservatism.  The American Populist Party should not be confused with the Populist Party of America or any of the several other American parties called "Populist", and it has no relationship to several historical parties of the same name.  The American Populist Party is a coalition of grass roots activists, ranging in political ideology from the left to the right, who are working to enact Constitutional reforms through the amendment process.

Oromo Peoples' Democratic Organization: The Oromo Peoples' Democratic Organization (OPDO) is a political party in Ethiopia, and part of the alliance with the Amhara National Democratic Movement, the South Ethiopian Peoples' Democratic Front and the Tigrayan Peoples' Liberation Front that forms the Ethiopian People's Revolutionary Democratic Front (EPRDF).  At the last legislative elections, 15 May 2005, the party was part of the Ethiopian People's Revolutionary Democratic Front, that won 327 out of 527 seats.

Salvadoran legislative election, 2009: A parliamentary election was held in El Salvador on 18 January 2009.  The leftist Farabundo Martí National Liberation Front (FMLN) was widely expected to win the most seats for the first time against the nationalist conservative Nationalist Republican Alliance (ARENA).  As a result of the election, the Revolutionary Democratic Front, a left-wing party founded by FMLN dissidents in 2006 with the same name and symbols as the historic FDR from the Salvadoran Civil War, was deregistered as a political party as it failed to gain either a seat or 50,000 votes, as necessary to sustain registration.  All parties contested the election in all departments, except for the FDR, which did not contest the election in three departments and stood jointly with the PDC in two others.

Revolutionary Democratic Front: The Revolutionary Democratic Front (Spanish: "Frente Democrático Revolucionario" , FDR) was a coalition of mass organizations in El Salvador.

Populism: Populism is a mode of political communication that is based on contrasts between the "common man" or "the people" and a real or imagined group of "privileged elites", traditionally scapegoating or making a folk devil of the latter.  Populists can fall anywhere on the traditional left–right political spectrum of politics, and can often be characterised as centrist where populists portray both bourgeois capitalists and socialist organizers as unfairly dominating the political sphere.

Siraj Fegessa: Siraj Fegessa is the incumbent Minister of Defense of Ethiopia.

Populist Party (United States, 1984): The Populist Party was a political party in the United States between 1984 and 1996.  It was conservative and often white nationalist in its ideology.

Salvadoran Democratic Front: Frente Democrático Salvadoreño (FDS) (Salvadoran Democratic Front) was a broad front of democratic organizations that was formed in El Salvador in March, 1980.
