Conclusion
Historically, areas like Tindouf and Béchar were part of Morocco’s sphere of influence prior to Ottoman rule. After 1962, new borders rooted in colonial occupation replaced those historical connections. Morocco’s ongoing claim to Western Sahara reflects its broader agenda: to safeguard what it considers its legitimate historical space. In contrast, Algeria upholds the French-imposed borders and contests any revision, framing itself as defender of regional stability and post-colonial norms. For those curious about Maghreb history, this complex interplay between medieval legacy, colonial boundaries, and modern diplomacy defines Algeria–Morocco relations to this day.
