The history of Aurich dates back to the 13th century, when the settlement of Aurechove was mentioned in a Frisian document called the Brokmerbrief in 1276. There are various hypotheses about the interpretation of the city name. It either refers to a person (Affo, East Frisian first name ) and his property (Reich) or it refers to waterworks on the fertile, water-rich lowland of the Aa (or Ehe) river, upon which the city was built; medieval realizations were Aurichove, Aurike, Aurikehove, Auerk, Auryke, Auwerckhove, Auwerick, Auwerck, Auwreke, Awerck, Awreke, Awrik, Auwerich and Aurickeshove .
In 1517, Count Edzard from the House of Cirksena began rebuilding the town after an attack. In 1539, the land authorities were brought together in Aurich, making it the county capital and, later, East Frisia, remaining the seat of the land authorities when East Frisia was inherited by the Kingdom of Prussia in 1744. After the Prussian Army was defeated in the Battle of Jena in 1807, Aurich became part of the Kingdom of Holland in 1808. In 1810, the Kingdom of Holland was annexed by France and Aurich was made the capital of the departmentEms-Oriental of the First French Empire. After Napoleon was defeated in 1814, it passed to the Kingdom of Hanover in 1815, and then was annexed by Prussia in 1866 and made part of the Province of Hanover.
Aurich's coat of arms is drawn by the blazon: "Arms: Landscape with chief two-thirds sky and base third earth, a shield Gules emblazoned with letter 'A' Or, an open-topped crown Or above, two growing trees Vert at sides. Crown: A battlement Gules with three merlons and two embrasures. Supporters: Two branches of mistletoe with leaves and berries Or.".
The coat of arms of the district with the same name is different.
