Much of the ancient Palace of Westminster in London burns to the ground in a devastating fire.

The blaze began after workmen burning obsolete wooden tally sticks in the House of Lords' furnaces overheated the flues, igniting the ancient timber-framed building. Flames engulfed most of the medieval palace overnight, watched by huge crowds along the Thames, though Westminster Hall was saved. The disaster led to the construction of the current Gothic Revival Houses of Parliament over the following decades.

The British colonial government partitions the province of Bengal, splitting it along largely religious lines.

Ordered by Viceroy Lord Curzon, the partition separated a Muslim-majority eastern Bengal from a Hindu-majority west, officially to ease administration of the vast province. Many Indians viewed it as a deliberate British attempt to weaken a growing nationalist movement by dividing communities. The backlash fueled mass protests and boycotts, and the partition was ultimately reversed in 1911.

Replacing the traditional ferry crossing at Kyle of Lochalsh, the bridge shortened journey times to the island considerably.

The tolls were eventually abolished by the Scottish Executive in 2004.
