The International Day of Parliamentarism is observed worldwide every June 30 to celebrate the role of national parliaments in implementing national and international plans and strategies. Established by the UN General Assembly in 2018, the day marks the anniversary of the Inter-Parliamentary Union (IPU), founded on June 30, 1889, by English MP William Randal Cremer and French economist Frédéric Passy. The IPU has played a significant role in promoting peace and cooperation among nations, contributing to the establishment of the Permanent Court of Arbitration. The observance aims to highlight the importance of strong parliaments in modern democracy, which are essential for passing laws that reflect the people's voice and holding governments accountable. The UN encourages all member states, national parliaments, and relevant organizations to participate in this observance, emphasizing the connection between national legislative bodies and international agreements.
