Peru entered the United Nations in the organisation's founding year
Background
The United Nations lists Peru's date of admission as 31-10-1945.
That places Peru among the original members who joined in the year the United Nations was founded.
The United Nations Charter had come into force earlier the same month.
Peru therefore counts as one of the founding members of the organisation.
Membership of the United Nations is open to peace-loving states that accept the obligations of the Charter.
Date of admission to the UN:
31-10-1945
Why it matters for exams: Dates of admission to the United Nations are a standard objective question in international organisations.
