The Piracy Act 1670

This law was enacted during the reign of Charles II and its full name was An Act to prevent the delivery up of Merchants Shipps, and for the Increase of good and serviceable Shipping. It came into being because the captains and crews of merchant vessels commonly refused to fight when attacked by pirates. The act stipulated that ships of 200 tons or more possessing at least sixteen guns were required to fight, as long as the pirate vessel didn’t have twice as many guns. Failing to resist would result in the commander being excluded from any further commands of English ships and even imprisonment.

Leisler’s Rebellion

It previously had the name New Amsterdam and was part of the Dutch colony New Netherlands. After the Director-General Peter Stuyvesant surrendered to English troops, the Dutch residents were permitted to remain in the colony and were granted religious freedom. The Dutch briefly regained the colony in 1673, but it became English again under the Treaty of Westminster, which ended the third Anglo-Dutch war. The governor of the colony of New York wasn’t keen to allow an elected representative assembly, instead letting it effectively be ruled by an oligarchy of wealthy merchants. In 1688 New York became a part of the Dominion of New England, governed by Sir Edmond Andros, who governed in an autocratically with no elected legislature.

Walker Art Gallery, Liverpool.In the 14th century Edward III (1327-1377) attempted to set up how admiralty courts should deal with piracy in A Remedy where a Merchant’s Good be robbed or perished on the Sea, but these were rather vague laws and there was often the problem of overlapping jurisdictions when dealing with such a crime. It was wasn’t until the reign of Henry VIII (1509–1547) that significant anti-piracy laws were enacted. Originally titled An Act for Pirates and Robbers on the Sea issued in 1535, it was renamed The Offences of Sea Act in 1536.

This act allowed crimes such as robbery and murder to be tried as if they occurred on land. They could be tried in any county in England in any court commissioned by the king under related common law provisions for these offences. Those found guilty of piracy and treason at sea could not only be sentenced to death, but also have their lands and possessions seized.…

Astrolabe

AstrolabeThis device is thought to have been first developed by the ancient Greeks, the term astrolabe meaning ‘star taker.’ It is a primitive inclinometer that calculates the altitude of the sun and stars to determine latitude. An astrolabe can be used for both astronomy and navigation at sea. Elaborate astrolabes can have etchings of how the sky looks at any given time or season. Sailors used this device by lining it up with the sun or a specific star, such as the North Star, in relation to the horizon in order to measure latitude vertically. This helped sailors to determine their location while at sea. Astrolabes came in a variety of shapes, such as a sphere or as flat plates and disks, and were made of metal, usually brass or iron, the former ensuring longevity at sea. A disadvantage was that astrolabes were cumbersome and could be difficult to use on the rolling deck of a ship.…
