The Spanish Civil War (1936-1939) is an extremely complex and controversial historical event, and its historical record is indeed influenced by multiple political biases and different ideological perspectives. 1. **Narratives of history from both sides**: After the war, the fascist regime ruled by Francisco Franco largely dominated the official narrative of the history of the Civil War. The Franco regime's narrative usually portrayed the Civil War as a struggle to defend traditional Spanish values and Catholicism against communism and anarchism. In contrast, the Republicans (losing side) and their supporters emphasized that the Civil War was an obstacle to democracy and reform. 2. **Post-Franco re-examination**: After Franco's death, especially after the beginning of Spain's democratization process (transition period), scholars and society became more open and diverse in their research and discussion of the Civil War. Scholars of different ideologies began to re-examine and study different aspects of the Civil War, which led to a more complex and multifaceted historical narrative. 3. **International perspective**: The Spanish Civil War was not only a domestic conflict in Spain, but also attracted widespread participation and attention from the international community. Therefore, scholars and political groups from different countries also interpreted and recorded it with their own political and ideological biases. 4. **Social memory and family heritage**: The memory of the Civil War within Spanish society is often influenced by personal family experiences and local history, which may differ from official or academic historical records. In summary, the historical record of the Spanish Civil War is indeed affected by multiple political biases, which makes it more complicated to conduct a fair and comprehensive study of it. However, over time, more and more studies have attempted to break the single narrative and analyze the Civil War from multiple perspectives, providing a more balanced and comprehensive historical perspective.
