September 11 attacks reshape US policy

Southern leaders proclaimed the Democratic Republic of Yemen during the civil war; international recognition did not follow.

Northern-led government forces captured Aden, ending the principal military phase of the 1994 civil war and entrenching grievances over southern exclusion.

Elections strengthened President Ali Abdullah Saleh’s General People’s Congress as major southern opposition forces remained marginalized.

Ali Abdullah Saleh won Yemen’s first direct presidential election in a contest with limited meaningful competition.

A suicide attack on the US destroyer USS Cole killed 17 American sailors; Washington expanded counterterrorism engagement with Yemen.

A US missile strike killed suspected al-Qaeda operative Qaed Salim Sinan al-Harethi and five others; the operation raised sovereignty and accountability questions.

The General People’s Congress maintained its parliamentary dominance amid opposition concerns over unequal political competition.

Fighting began between government forces and followers of Hussein Badreddin al-Houthi, laying the foundation for successive wars in northern Yemen.

Government forces killed Hussein Badreddin al-Houthi; the movement persisted and later reorganized under other leaders.

A second round of fighting deepened the conflict between the Yemeni state and the Houthi movement, harming civilians and displacing families.
