The UN is known as the acronym for United Nations Organization, which is heir to the League of Nations of the 1920s. It is an international organization of nation-states based on the principle of sovereign equality.

According to the founding charter (Charter of the United Nations), which entered into force on October 24, 1945, the UN was established on that day to maintain international peace and security, as well as promote bonds of union and friendship between member countries, strengthen cooperation among all countries for the solution of economic, social, cultural or humanitarian problems, and promote respect for human rights and fundamental freedoms.

The UN was originally founded by 51 member countries, today it has increased to 192. Part of the commitments made by these member states is to comply with the obligations they have assumed and resolve international disputes through peaceful means, suppressing the threat or the use of force.

One of the most important steps in the history of the UN was in 1948, in which the Universal Declaration of Human Rights was established, an emblematic milestone of the recognition, description and consecration of the rights that make up the essence and dignity of the human being. for the sole fact of being worldwide.

It could be said that the United Nations is not a world government, nor does it establish laws. It only provides the necessary means to find solutions to international conflicts and formulate policies on issues that affect us all. All Member States, large and small, rich and poor, with different political views and social systems, have a say in this process.

The structure of the UN consists of 6 main bodies, five of them at its headquarters in New York (National Assembly, Security Council, Economic and Social Council, Trusteeship or Trusteeship Council and the General Secretary); and the sixth is the International Court of Justice which is in The Hague (The Netherlands).

Likewise, the UN includes various specialized agencies such as the WHO (World Health Organization), UNESCO (Organization for education, science and culture), ILO (International Labor Organization), IMF (International Monetary Fund), World Bank etc There are also programs and funds, such as the Office of the United Nations High Commissioner for Refugees (UNHCR), the United Nations Children’s Fund (UNICEF), among others.

It should be noted that one of the central issues of the UN in this new century is to provide assistance resources for the least developed countries through the Millennium Development Goals (MDG) program, which it seeks to achieve by 2015: eradicate extreme poverty and hunger, target primary education, promote gender equality, reduce child mortality, improve maternal health, combat AIDS, ensure a better environment, and foster a global partnership for development.
