How were political movements in Algeria both successful and damaging after world war 2?

After World War II, political movements in Algeria, particularly the nationalist movement led by the National Liberation Front (FLN), were successful in mobilizing widespread support against French colonial rule, ultimately leading to independence in 1962. However, this struggle also resulted in significant violence and loss of life during the Algerian War of Independence, leaving deep social and economic scars. Additionally, the post-independence political landscape was marred by authoritarianism and civil conflict, undermining the initial aspirations for democracy and social justice. Thus, while these movements achieved independence, they also instigated long-term challenges for the nation.
