Geopolitical boundaries refer to the lines that define the territorial limits of countries, states, or regions. These boundaries can be based on natural features like rivers and mountains, or they can be established through historical agreements, wars, or colonization. They play a crucial role in determining governance, resource distribution, and cultural identity within a specific area. These boundaries can change over time due to various factors, including political negotiations, conflicts, or shifts in power. For example, the breakup of the Soviet Union in the early 1990s led to the creation of several new countries, each with its own geopolitical boundaries.
