International Olympic Committee

Structure and membership

The IOC is an international, non-governmental, non-profit association. It brings together individual members, representatives of National Olympic Committees (NOCs) and International Federations (IFs), and works with Organizing Committees for the Olympic Games. The IOC recognizes more than 200 NOCs worldwide, which represent national teams and athletes within the Olympic Movement. Decisions are guided by the Olympic Charter, a set of rules and principles that defines the organization, role and mission of the IOC and affiliated bodies.

Functions and activities

The IOC has several core responsibilities that sustain the Olympic Games and broader sporting values. These include:

• Selecting host cities for the Summer and Winter Olympic Games and overseeing the bidding and preparation processes.
• Setting and enforcing the Olympic Charter, including eligibility and competition rules in coordination with IFs and NOCs.
• Promoting Olympism — the movement that combines sport with education and culture — through funding, education programs and development grants such as Olympic Solidarity.
• Working on integrity and fairness in sport, including efforts to combat doping and corruption in partnership with other bodies.

History and development

The IOC emerged from a late‑19th century effort to revive ancient Greek athletic traditions for modern international competition. The first modern Olympic Games were staged in 1896, and the movement expanded over the 20th century to include winter sports, youth events and a growing number of disciplines. Over time the IOC evolved from a small committee to a complex organization interacting with governments, sports federations, broadcasters and sponsors.

Criticism, reform and governance

Throughout its history the IOC has been praised for uniting diverse nations through sport but has also faced criticism. Concerns have included the rising cost and complexity of hosting the Games, doping scandals, and allegations about the transparency of host-city selection. These issues prompted governance reforms, stronger ethics rules and cooperative initiatives with independent bodies to improve oversight and athlete protection.

Symbols, legacy and importance

The IOC is central to several enduring symbols of the Olympic Movement, such as the five-ring emblem and the torch relay. Beyond staging the Olympic Games, its work influences international sports development, promotes volunteerism and helps fund athletic programs in nations with fewer resources. The IOC continues to adapt to changing expectations about sustainability, inclusion and athlete welfare while seeking to keep sport a force for peaceful international engagement.
