Background: Knights, based in Malta since 1530, harassed Ottoman shipping. Suleiman launched a massive invasion.
Siege: Ottomans landed, built siegeworks, assaulted the Knights' fortifications in Valletta. Despite being outnumbered, the Knights repelled every assault and launched counterattacks.
End: A Spanish relief fleet arrived in September; Ottomans withdrew.
Significance: Halted Ottoman expansion in the Mediterranean; celebrated as a symbol of resilience.
