LSAP reflects a commitment to social democracy with a focus on fairness, social security, environmental sustainability and education. Its policies aim to meet the diverse needs of Luxembourg's population and create a society that provides opportunities and support for all citizens.

The LSAP staunchly upholds the belief that a society without freedom is a state devoid of human dignity. Individuals should have the autonomy to lead their lives as they see fit, as long as their choices align with socially responsible behavior.
Party advocates that the wealthiest nations should display solidarity with the less affluent in their quest to establish a livable society. Wealthy Northern Europe should help the economically disadvantaged South, and wealthy industrialized countries should help the developing ones.
Solidarity is the lifeline for the weakest members of society, according to the LSAP. Those in need should be able to rely on social solidarity and receive support.
Party stresses that poverty serves as a breeding ground for terrorism, as societies faced with hunger and despair have limited prospects for peace. At the individual level, however, security is also important. Social solidarity is essential to ensure citizens' security in old age, sickness, unemployment and other situations.

Brief history of the party

The Luxembourg Socialist Workers' Party is one of the oldest parties in the country. Since its foundation in 1902, it has been a popular choice among voters and has helped shape the country's modern politics.

Foundation of the LSAP: 1902-1959

  • Founded in 1902, the Luxembourg Socialist Workers' Party (LSAP) evolved into its current form, the "Lëtzebuerger Sozialistesch Arbechterpartei," in 1945.
  • In 1951, the LSAP entered the Luxembourg government in coalition with the CSV, marking its second government participation (the first being in 1937 as the "Parti social-démocrate"). The LSAP remained in the government as a coalition partner until 1959.

Continued coalition, challenges and return: 1964-1983

Henry Cravatte
Vice Prime Minister of Luxembourg in 1964.
  • The LSAP returned to government in 1964, with Henry Cravatte serving as Vice Prime Minister. While the LSAP has never held the position of Prime Minister, it has consistently acted as a coalition partner alongside DP and CSV in most government formations since 1951.
  • After losing the 1969 elections, internal debates emerged within the LSAP regarding its future, including whether to engage in coalitions with CSV or the Communist Party at the local level. 
  • In 1970, internal turmoil led to the departure of party president Henry Cravatte and approximately 15% of members, forming a second Luxembourgish social-democratic party, the "Sozialdemokratesch Partei," which existed until 1983. Henry Cravatte eventually returned to the LSAP.

Ongoing government participation: 1984 to present

Jean Asselborn
Minister for Foreign and European Affairs of Luxembourg since 2004. Deputy Prime Minister from 2004 to 2013.
  • Since 1984, except for the period from 1999 to 2004, the LSAP has been part of the Luxembourg government under Prime Ministers Jacques Santer and Jean-Claude Juncker, with Vice Prime Ministers Jacques Poos and Jean Asselborn.
  • Starting in 1999, the LSAP has been represented in nearly all municipal councils, except for Kopstal. The party secured 139 seats in 1999 and 165 seats in 2005. After winning a total of 211 seats across 116 Luxembourgish municipalities in 2005, the LSAP placed 16 mayors in the councils of "Proporz-Gemengen" and ten more in other municipalities.
