General elections to the Cortes Generales were held in Spain on 9 April 1916. At stake were all 409 seats in the Congress of Deputies. Though formally competitive, the 1916 general election was held under the customary system of Turno Pacifico; in accordance with a long-standing power-sharing arrangement, elections (under influence by machine bosses called caciques) served as a rubber stamp for a routine handover of power initiated by the King. The 1916 election, as expected, sanctioned the pre-arranged handover from the Conservatives to the Liberals.

1940 — Battle of Drøbak Sound

The Battle of Drøbak Sound took place in the northernmost part of the Oslofjord on 9 April 1940, on the first day of the German invasion of Norway. It was the start of the war in Western Europe—and an end to the "Phoney War". Oscarsborg Fortress near Drøbak engaged a German fleet sailing up the Oslofjord with the objective of seizing the Norwegian capital and capturing Haakon VII, the Norwegian king, and his government. At the time of the battle, the ageing fortress' Main Battery of guns was over 40 years old and the installation had been relegated to training coastal artillery servicemen, leading the Germans to disregard the fortress' defensive value.

1992 — United Kingdom general election, 1992

The United Kingdom general election of 1992 was held on 9 April 1992, and was the fourth consecutive victory for the Conservative Party. It was the last outright win for the Conservatives until 2015. This election result took many by surprise, as opinion polling leading up to the election day had shown the Labour Party, under leader Neil Kinnock, consistently, if narrowly, ahead. John Major had won the leadership election in November 1990 following the resignation of Margaret Thatcher. During his term leading up to the 1992 election he oversaw the British involvement in the Gulf War, introduced legislation to replace the unpopular Community Charge with Council Tax, and signed the Maastricht treaty.
