• Prime Minister of Sweden Tage Fritiof Erlander, 1901

Ascending to the World War II coalition government in 1944, Erlander rose unexpectedly to leadership upon the death of Prime Minister Per Albin Hansson in October 1946, cementing the position of the Social Democratic Party as the virtual government of Sweden. Known for his moderation, pragmatism and self - irony, Erlander constantly sought approval from the liberal - conservative opposition for his policies, de facto dropping all pretenses of wide scale nationalizations whilst introducing reforms such as universal health insurance, pension additions and a growing public sector while stopping short of raising tax levels above the average OECD levels at the time. In 1951 - 1957, he espoused a coalition government with Peasants' League chairman Gunnar Hedlund in order to secure majority and stability, led by himself.

In foreign policy, he initially sought an alliance of Nordic countries, but without success, instead maintaining strict neutrality while building up among the most impressive armed forces in the world (surpassed only by the United States, the Soviet Union and Israel in terms of per capita spending), making the Swedish Air Force the third largest in the world, while ultimately rejecting nuclear capability, signing the nuclear non - proliferation treaty in 1968. Erlander's mandate coincided with the post World War II economic expansion, in Sweden known as the record years.

Resigning after the Swedish general election, 1968, his seventh and most successful general election in which his Social Democrats surpassed all four opposition parties in terms of seats, in the midst of constitutional reforms, Erlander was succeeded by his long time novice and friend, Olof Palme. Dying on June 21, 1985 at age 84, Erlander's funeral procession crossed the country from Stockholm to his home town of Ransäter in triumph for his final interment.

He was born in Ransäter, Värmland County, as son of the school teacher Erik Gustaf Erlander (1859 – 1936). His mother was Alma Nilsson (1869 – 1961). As a student at Lund University he was heavily involved in student politics and met many radical students. He graduated in political science and economics in 1928. Erlander was a member of the editorial staff of the encyclopedia Svensk Upplagsbok from 1929 to 1938. In 1930 he married Aina Andersson, who became Aina Erlander.

Tage Erlander was elected to the municipal council in Lund in 1930 and became a member of parliament in 1932, and was appointed a State Secretary at the Ministry of Social Affairs in 1938. As State Secretary at the Ministry of Social Affairs, Erlander was one of the most senior officials responsible for the establishment of internment camps in Sweden during World War II. In the camps, which were kept secret from the Swedish public, people from various ethnic minorities as well as political dissidents were interned, particularly Communists and Soviet Union sympathizers.

In 1942, State Secretary Erlander together with then Minister for Social Affairs Gustav Möller initiated a nation wide registration of the Swedish Travelers, a branch of the Romani people that has been resident in Sweden for 500 years. The purpose of the registration was, according to a newspaper article, to make the base for "radical measures" against this "bottom layer of the Swedish population". In Norway, similar lists were established that were handed over to the Nazis during the German occupation of Norway.

Erlander ascended to the cabinet in 1944 as minister without Portfolio, a post he held to the next year, when he became Minister for Education. When Prime Minister Per Albin Hansson suddenly died in 1946, Erlander was unexpectedly chosen as the successor and subsequently also as the leader of the party.

Retaining the positions of the Social Democrats from a potent Liberal opposition under Bertil Ohlin in his first election, he later formed a coalition with the Center Party, at the time the Peasants' League between 1951 and 1957. His working relationship with the party's leader, Gunnar Hedlund (Minister for Home Affairs in the coalition government), is known to have been good.

Erlander coined the phrase "the strong society", describing a society with a growing public sector taking care of the growing demand on many services that an affluent society creates. The public sector, particularly its welfare state institutions grew considerably during his tenure as Prime Minister, while nationalizations were rare. In order to maintain employment for his vast electorate and Swedish sovereignty as a non - NATO member, the armed forces was greatly expanded, reaching an impressive level by the 1960s, while nuclear capability was ultimately dropped after outcries, not least from the Social Democratic Women's League.

The question of nuclear weapons as a means to deter a possible attack remained a divisive factor in Swedish society and among Social Democrats and prompted diplomatic agreements with the United States guaranteeing intervention in that case of an invasion. Sweden signed the nuclear non - proliferation treaty in 1968, dropping all pretenses of developing a nuclear weapon.

Resigning at 68 in 1969, with an absolute majority for the Social Democrats in the second chamber since 1968, Erlander was succeeded by 42 year old Olof Palme, who, although more radical, had in many ways been Erlander's student and protege. From 1972 to 1982 Erlander published his memoirs in six volumes. He died on 21 June 1985 in Stockholm and, after a ceremony, was returned to Ransäter, Värmland, in a triumphant procession for the final rest.

He was the father of the mathematician Sven Erlander, who, since 2001, has published his father's diaries.
