Leer had been a settlement long before it was first mentioned in written documents. Originally the city was situated at a meander near the mouth of the river Leda into the Ems, which is still the center of the town today. Even though Leer is some 30 km (19 mi) away from the coast, it can be reached by large ships via the Ems. Leer lies close to the Dutch border; the district of Leer shares a border with the Dutch province of Groningen.
There are many traces of early settlements in the area, including crude flint tools that are dated back to roughly 3200 BC.
In 791 AD Saint Ludger built the first chapel in East Frisia at the western edge of the settlement Leer, then still named Hleri after feetlot, willow. This chapel is mentioned for the first time in a written document from 850 AD.
During the 14th and 15th centuries, Leer was home town of the Ukena family which was one most influential East-Frisian chieftain families of that time. The town profited from the trade with the Hanse, and a fortress Leerort was built.
In 1508, Count Edzard obtained the official right to host a market, which started the tradition of the "Gallimarkt," which is now an annual fair. In 1744 East Frisia fell to Prussia, then ruled by Frederick the Great. Town privileges were awarded in 1823 by George IV, King of Hanover.
In 1854 Leer became connected to the "Hannoversche Westbahn" railway, which at that time connected Emden and Rheine in the Ruhr area. In 1856, the Westbahn was connected to the central German railway network.
On 1 October 1955, Leer received the status of an independent city.
Since 1964 the city's government has been led by the Social-Democratic Party SPD. The major opposition parties are the Christian Democratic Union Party CDU, the Green Party and the AWG, an independent local party. The mayor of Leer is Beatrix Kuhl.

Leer is a traditional Protestant city and home to both the Lutheran and Reformed churches. The German Reformed Church has its head office in Leer. Furthermore, Leer offers an unusually large variety of smaller religious communities, especially Baptists, Mennonites, Methodists, Adventists and Mormons. Even though Eastern Frisia is a mainly a Protestant region, there is a small Roman Catholic community in Leer.
Economics and infrastructure
Two autobahns (freeways) cross north of Leer, the A 28 (Leer - Bremen) and the A 31 (Emden - Oberhausen, Ruhr Area). The city itself has three junctions to the autobahns. Leer railway station is a relay station between Groningen and Bremen in the west-east direction and the South and Emden harbour (with a large VW factory and shipping facilities) in the north. The airfield Leer-Papenburg north of the city offers limited passenger flights to nearby airfields, most notably the East Frisian Islands. The closest international airport is Bremen International Airport.
Leer is home to many German shipping companies — about 20 per cent of the German merchant fleet are registered in Leer. The Bünting group  is based in Leer and is one of the city's main employers. Although Bünting owns several German supermarket chains, the company is best known for their tea, which is available all over Germany.
Each year in autumn the Gallimarkt is held. Traditionally a cattle-market, the Gallimarkt is now one of the largest fairs in Northwest Germany.
In Leer there are seven primary schools and numerous secondary schools. The two gymnasiums, Teletta Gross Gymnasium and Ubbo-Emmius-Gymnasium, educate more than 1,500 pupils each and are two of the largest grammar schools in Lower Saxony. The Navigation School is now faculty of the Hochschule Emden - Leer (University of applied science). The town also offers education at two vocational schools.
