How did an English police force become known as “Scotland Yard”?
In the tenth century, in an effort to stop hostilities between their two countries, the English gave a Scottish king land in London with the provision that he build a castle on it and live there for a few months every year. Seven centuries later, with the two nations united under one king, the land returned to English ownership. In 1829, the London police took up residence on the land, which by then was known as Scotland Yard.

Why is the American presidential home called the “White House”?
From 1800, when John Adams became the first president to inhabit it, until 1814, when the British burned it because the Americans had torched Toronto, the presidential building was a grey Virginia freestone. It was painted white to cover up the fire damage done by the British. It wasn’t officially called the White House until Teddy Roosevelt began printing its image on the executive mansion stationery in 1901.

That wall was situated on the exact spot that we now know as the financial centre of the world: Wall Street.

Why are the people of Oklahoma called “Sooners”?
In the 1800s, when the American West was first opened, the early pioneers were offered free land east of the Rockies, but to ensure fairness, they could only stake out forty acres after a race to the region on a specific date and time. Those heading for Oklahoma who jumped the gun and settled on the best land before the official start of the race were cheating and were called “Sooners” because they arrived “sooner” than those who obeyed the law.

How did the centre of the song publishing industry become known as “Tin Pan Alley”?
Tin Pan Alley is an actual place in New York City. It’s the nickname for the side streets off Times Square, where for generations music publishers have auditioned new songs. The name came from the late 1800s, when the awful sound of cheap tinny pianos coming through the open office windows of hundreds of publishers was likened to the beating of tin pans.
