Nicaean Sieges
- An unsuccessful attempt in 1235, by Bulgarian and Nicaean forces, to retake the city.
- An attack on Constantinople is implied by George Akropolites's account for 1248, but no details are known.
- A second unsuccessful siege of Constantinople and Galata, in January-April 1260.
- In 1261, a small force of Nicaean troops under Alexios Strategopoulos gained entry into the poorly defended Latin capital, ending the Latin Empire and restoring Byzantine rule to the City. Most Latin troops defending the city were absent on campaign, and the Emperor fled without putting up any resistance; there was no siege.
