Potential influence on Native American languages: The British colonization of North America led to the near-extinction of several Native American languages. A similar effect might have occurred in South America, resulting in fewer indigenous languages being spoken today.
Trade and economic ties: The English had already established a vast colonial network and global trade routes by the time they began colonizing the Americas. South American trade would likely have been more closely integrated with the British Empire's global economy, shifting economic dynamics.
Influence on literature and the arts: The absence of Spanish and Portuguese cultural influences would have a profound impact on literature, music, and art. English literary and artistic styles would likely have become dominant, shaping South American cultural expression.
Different geopolitical alliances: The geopolitical alliances formed by an English-dominated South American would have been different. Historical conflicts, such as those with Spain, might have taken on different dimensions.
Religious makeup: The English settlement of North America was characterized by a diversity of religious beliefs, including a significant Protestant presence. The religious landscape in South America could have been shaped by Protestant denominations rather than Catholicism, leading to a different distribution of religious groups.
Settlement patterns: The British established various types of settlements in North America, including coastal trading hubs and agricultural colonies. The settlement patterns in South America might have reflected similar choices based on economic and strategic considerations.
These scenarios are speculative and depend on a complex set of factors that could vary in a different historical context. However, they highlight some potential consequences had the English been prominent colonizers in South America.
