==== England ====
* February &ndash; [[South England flood of February 1287|South England flood]]: A large storm hits the south coast, this has a powerful effect on the [[Cinque Ports]], two of which are hit ([[Hastings]] and [[New Romney]]). The storm destroys Old [[Winchelsea]] on [[Romney Marsh]] and nearby [[New Romney#History|Broomhill]]. The course of the [[River Rother, East Sussex|Rother River]] is diverted away from New Romney, which is almost destroyed, ending its role as a port; the Rother runs instead to the sea at [[Rye, East Sussex|Rye]] – whose prospects as a port are enhanced. A cliff collapses at Hastings, ending its role as a trade harbor and demolishing a part of [[Hastings Castle]]. New Winchelsea is established on higher ground.<ref>{{cite book|first=Paul|last=Simons|title=Since Records Began|location=London|publisher=Collins|year=2008|isbn=978-0-00-728463-4}}</ref>
* [[June 8]] &ndash; Welsh forces led by [[Rhys ap Maredudd]] revolt in [[Wales in the Middle Ages|Wales]] against King [[Edward I of England|Edward I]] ('''Longshanks'''). Although Maredudd has assisted the English in the past, he accuses Edward of treating him unfairly over taxes. The rebels burn several towns, including [[Swansea]] and [[Carmarthen]]. They capture most of [[Ystrad Tywi]], heartland of [[Deheubarth]] (the revolt will not be suppressed until [[1288]]).
* Summer &ndash; Edward I ('''Longshanks''') replies to the Welsh rebellion by raising an army at [[Gloucester]] commanded by [[Edmund, 2nd Earl of Cornwall|Edmund of Almain]]. The English forces besiege [[Dryslwyn Castle]], which lasts for three weeks before the castle falls after the curtain walls are undermined. Rhys ap Maredudd manages to escape and goes into hiding before the stronghold is finally captured in late September.
* December &ndash; Parts of [[Norfolk]] are flooded, the port of [[Dunwich]] in [[Suffolk]] is further devastated, and in [[The Fens]] through the storm and the violence of the sea, the monastery of [[Spalding, Lincolnshire|Spalding]] and many churches are overthrown and destroyed: "The whole country in the [[parts of Holland]] was, for the most part, turned into a standing pool so that an intolerable multitude of men, women and children were overwhelmed with the water, especially in the town of [[Boston, Lincolnshire|Boston]], a great part thereof was destroyed."<ref name=wheeler>{{Wheeler1896|page=27}}, quoting ''Stow's chronicle'' of 1287</ref>
