A revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. The revolver allows the user to fire multiple rounds without reloading after every shot, unlike older single-shot firearms. After a round is fired the hammer is cocked and the next chamber in the cylinder is aligned with the barrel by the shooter either manually pulling the hammer back or by rearward movement of the trigger. Revolvers still remain popular as back-up and off-duty handguns among American law enforcement officers and security guards and are still common in the American private sector as defensive and sporting/hunting firearms. Famous revolvers models include the Colt 1851 Navy Revolver, the Webley, the Colt Single Action Army, the Colt Official Police, Smith & Wesson Model 10, the Smith & Wesson Model 29 of Dirty Harry fame, the Nagant M1895, the Colt Python. Though the majority of weapons using a revolver mechanism are handguns, other firearms may have a revolver action.

These include some models of grenade launchers, shotguns and cannons. Revolver weapons differ from Gatling-style rotary weapons in that in a revolver only the chambers rotate, while in a rotary weapon there are multiple full firearm actions with their own barrels which rotate around a common ammunition feed. In the development of firearms, an important limiting factor was the time required to reload the weapon after it was fired. While the user was reloading, the weapon was useless providing an adversary the opportunity to kill or injure the user. Several approaches to the problem of increasing the rate of fire were developed, the earliest involving multi-barrelled weapons which allowed two or more shots without reloading. Weapons featured multiple barrels revolving along a single axis. During the late 16th century in China, Zhao Shi-zhen invented the Xun Lei Chong, a five-barreled musket revolver spear. Around the same time, the earliest examples of what today is called a revolver were made in Germany.

These weapons featured a single barrel with a revolving cylinder holding the ball. They would soon be made in numerous designs and configurations. However, these weapons were difficult to use and prohibitively expensive to make, as such they were not distributed. In 1836, an American, Samuel Colt, patented a popular revolver which led to the widespread use of the revolver. According to Samuel Colt, he came up with the idea for the revolver while at sea, inspired by the capstan, which had a ratchet and pawl mechanism on it, a version of, used in his guns to rotate the cylinder by cocking the hammer; this provided a reliable and repeatable way to index each round and did away with the need to manually rotate the cylinder. Revolvers proliferated due to Colt's ability as a salesman, but his influence spread in other ways as well. Early revolvers were caplocks and loaded as a muzzle-loader: the user poured black powder into each chamber, rammed down a bullet on top of it placed percussion caps on the nipple at the rear of each chamber, where the hammer would fall on it.

This was similar to loading a traditional single-shot muzzle-loading pistol, except that the powder and shot could be loaded directly into the front of the cylinder rather than having to be loaded down the whole length of the barrel. This allowed the barrel itself to be rifled, since the user wasn't required to force the tight fitting bullet down the barrel in order to load it; when firing the next shot, the user would raise his pistol vertically as he cocked the hammer back so as to let the fragments of the burst percussion cap fall out so as to not jam the mechanism. Some of the most popular cap-and-ball revolvers were the Colt Model 1851 "Navy" Model, 1860 "Army" Model, Colt Pocket Percussion revolvers, all of which saw extensive use in the American Civil War. Although American revolvers were the most common, European arms makers were making numerous revolvers by that time as well, many of which found their way into the hands of the American forces, including the single action Lefaucheux and LeMat revolver and the Beaumont–Adams and Tranter revolvers, which were early double-action weapons, in spite of being muzzle-loaders.

In 1854, Eugene Lefaucheux introduced the Lefaucheux Model 1854, the first revolver to use self-contained metallic cartridges rather than loose powder, pistol ball, percussion caps. It is a pinfire revolver holding six rounds. On November 17, 1856, Daniel B. Wesson and Horace Smith signed an agreement for the exclusive use of the Rollin White Patent at a rate of 25 cents for every revolver. Smith & Wesson began production late in 1857 and enjoyed years of exclusive production of rear-loading cartridge revolvers in America, due to their association with Rollin White, who held the patent and vigorously defended it against any perceived infringement by other manufacturers. Although White held the patent, other manufacturers were able to sell firearms using the design, provided they were willing to pay royalties. After White's patent expired in April 1869, a 3rd extension was refused. Other gun-makers were allowed to produce their own weapons using the rear-loading method, without having to pay a royalty

Anna Leonie is a towed boat on the Saar maintained museum ship in Saarland, Germany built in 1925–26. Horse-drawn, she was from around 1939, towed by a tractor. Towed vessels on the Saar were designated Penichen; until 1992 there were towpaths along the waterways. After these were eliminated the Anna Leonie was unable to be used any longer, because she remained without her own drive motor. In any case, she had lain tied up since the 1960s alongside the Congresshalle in Saarbrücken; the Anna Leonie was ordered from the shipyard of the Gebrüder Schäfer in Völklingen on order from the boatman Johann Kind. He lived on board with his family, named the ship after his two youngest daughters, his son continued to live on the ship until his death in 1987. By 2006 the Anna Leonie was the last of its kind and it was determined that it should continue to be maintained; the Saar fishermen's association was able to purchase her in 2007, in 2008 send her to a shipyard for restoration. At the end of 2009 an exhibition "Ocean of the Future" was presented.

In the future she will be used as an exhibition and museum ship along the Saar

The 2013–14 GMHL season was the eighth season of the Greater Metro Junior A Hockey League. The twenty teams of the GMHL played 42-game schedules. Starting in February 2014, the top teams of the league played down for the Russell Cup, emblematic of the grand championship of the GMHL. Since the GMHL is independent from Hockey Canada and the Canadian Junior Hockey League, this is where the GMHL's season ended. In the end, second year team Bradford Bulls defeated the defending champion Bradford Rattlers in the "Sidewalk Series" 4-games-to-1 to win their first Russell Cup as GMHL playoff champions.
