The BRICS nations which are South Africa, Brazil, Russia, India, and China have become central to debates about the future of global order. When considered alone, this group makes up around half of the world's population and are a quickly growing part of the global economy. The rise of this bloc is not only about making the economy bigger; it is also about trying to change the rules that govern the world. The New Development Bank and other groups that work together to communicate their views in international venues are examples of a long-standing desire to offer alternatives to Western-led methods of financing and development. All of these nations are examples of the desire to offer choices. This study examines the BRICS nations as a collective beyond mere economic cooperation. The influence of the BRICS nations is closely connected to issues of sovereignty, identity, and legitimacy. The papers utilize qualitative analysis of summit declarations and policy addresses, in conjunction with quantitative statistics from the World Bank, the International Monetary Fund, and the United Nations Conference on Trade and Development (UNCTAD) related to trade, investment, and economic growth. The results show that the BRICS countries have made significant contributions to a more multipolar system and have started new ways for institutions to work together. However, these improvements are typically limited by differences in size, governance, and strategy within the BRICS group. The study found that the BRICS nation are prime examples of the advantages and limitations of a global system that can adapt. It is crucial to study the rise of new powers and their impact on the international order in the 21st century from political science, economics, and social philosophy.
