January 8 – Guelph forces, led by the Genoese leader François Grimaldi (il Malizia), storm and capture the Rock of Monaco. François, disguised as a Franciscan friar, gains entry to the city, and opens the gates for his soldiers. He seizes the castle with his stepson Rainier I, an event that is commemorated on the coat of arms of Monaco. Rainier becomes the first sovereign ruler of the House of Grimaldi in Monaco; he rules initially until 1301, but the family will be ruling there into the 21st century.
April 14 – King Edward I of England makes an appeal outside Westminster Hall for support for the war against France. He apologizes for the high tax demands he has previously levied. Edward asks the Barons (some 1,500 knights) to swear allegiance to his 12-year-old son, Prince Edward of Caernarfon. Aware of the dangers of the opposition to his power, Edward appears before a large crowd and receives total loyalty.
Summer – Edward I of England orders a punitive expedition against the rebellious Scots. At Roxburgh, an army of some 9,000 men (including 2,000 cavalry) led by John de Warenne is assembled. Meanwhile, William Wallace leaves the forest of Selkirk with reinforcements and turns his attention north of the River Forth.[4]
July – In Scotland, a group of nobles forms a confederacy (organized by Robert Wishart, bishop of Glasgow), but are defeated by English troops at Irvine. An agreement of submission to Edward I of England is signed by the future Scottish king Robert the Bruce and other Scottish leaders.
August 22 – Edward I of England leads an expedition to Flanders. He moves with an army (some 8,000 men) supported by 800 knights to Ghent and makes the city his base of operations in Flanders.
October–November – Scottish forces led by William Wallace begin raids in Northumberland and Cumberland. During a ceremony at Selkirk, Wallace is knighted and appointed Guardian of Scotland.[6] (Contradicts First Scottish War of Independence that cites William Wallace as having been made a knight and Guardian of Scotland in March, 1298)
Winter – Edward I of England accepts a truce proposed by King Philip IV of France ("the Fair") and leaves Flanders. He returns to London and prepares a campaign against William Wallace in Scotland.
