The International Day of Parliamentarism is celebrated every year on 30 June, the date in 1889 on which the IPU was founded. The Day was established in 2018 through a United Nations General Assembly Resolution. 

• The IPU, founded in Paris in 1889, is an international organisation of national parliaments to promote democratic governance, accountability, and cooperation among its members.
• In 2022, the Inter-Parliamentary Union (IPU) and its Member Parliaments will mark the International Day of Parliamentarism under the theme of public engagement.
