"Russian Germans" refers to ethnic Germans who settled in Russia, particularly during the 18th and 19th centuries. Many were invited by Catherine the Great to populate and cultivate the Volga region. They maintained their distinct culture, language, and traditions while adapting to their new environment. Over time, Russian Germans faced various challenges, especially during the Soviet era, when many were persecuted and deported. Today, some descendants still live in Russia, while others have migrated to countries like Germany and Canada, preserving their unique heritage and contributing to the cultural diversity of their new homes.
