When was the ILO formed and why?

Hint: The International Labour Organisation is a United Nations specialised agency to serve the demands of the labour force by improving working conditions and living standards in all member states of the UN. It does so representing the voice of the workforce and developing policies and programs for their benefit. The headquarters of the International Labour Organisation is located in Geneva, Switzerland. The organisation comprises the International Labour Conference, the Governing Body and the International Labour Office under the Director-General of the ILO.

Complete step by step solution:
The International Labour Organisation was created in 1919 as an agency of the League of Nations under the Treaty of Versailles after the First World War. The Constitution of the ILO was drafted by the Labour Commission in 1919 and the organisation strived to establish universal peace based on social justice. Some of its goals were to improve regulation of working time and conditions, preventing unemployment, seeking to provide an adequate living wage, guaranteeing equal pay for equal work and ensuring social protection of workers, children, young persons and women. The ILO played a major role in combating the widespread unemployment caused during the Great Depression. Although the League of Nations was dissolved and replaced by the United Nations in 1946, the ILO was the only functioning organisation that was carried forward and it became the first affiliated agency of the United Nations. With an extended membership after the Second World War, the ILO addressed new social issues in poorer countries like child labour and degraded conditions of work.

Note: In 1969, the International Labour Organisation was awarded the Nobel Peace Prize for introducing legislation and reforms to ensure healthy working conditions in all member states.
