Aargau is one of 26 such cantons. It is located in the northern part of Switzerland. The region sits along the lower course of the Aare River. This river gave the canton its name, which means "Aare province."

Today, Aargau is one of the most densely populated regions in the country. It is divided into eleven distinct districts. The capital city of the canton is Aarau.

The history of this land began long before the modern canton existed. As early as 200 BC, the Helvetians lived here. The Helvetians were a tribe of Celts. Later, the Romans occupied the territory. They built a major settlement called Vindonissa. This settlement was located near the modern town of Brugg.

By the 6th century, the Franks had taken control of the area. For many centuries, the region served as a disputed borderland. It sat between the duchies of Alamannia and Burgundy within the Frankish Empire.

During the Middle Ages, power in Aargau was divided among many groups. The von Wetterau family held the countship from 750 until 1030. By the year 1200, the Zähringen dukes and the Habsburg houses controlled much of the region. The Habsburgs were a powerful family that held much of the land. However, the Swiss Confederacy changed everything in 1415. The Confederacy used an imperial ban against Frederick IV of Habsburg as a reason to invade. They quickly conquered towns like Aarau, Lenzburg, Brugg, and Zofingen.

They also captured most of the Habsburg castles.

After the conquest, the territory was split into different administrative zones. One part was called the Unteraargau, or Bernese Aargau. This area was ruled directly by the city-state of Bern. In the late 18th century, Bern encouraged industrial development here. This led to massive population growth. Between 1764 and 1798, the population grew by 35 percent.

Another area was known as the Freie Ämter, or free bailiwicks. These were subject lands governed by the Swiss Confederation. The Freie Ämter were often split by religious conflicts. Wars between Reformed and Catholic armies used these lands as staging grounds.

The County of Baden was another unique administrative region. It was a shared territory, or condominium, of the entire Old Swiss Confederacy. This area had a very complex legal structure. Over 30 different nobles held rights to hold courts in small pieces of land. These overlapping jurisdictions caused many conflicts. The administration changed frequently because governors were appointed every two years. This made it difficult to create long-term economic policies. For a long time, the area lacked factories or large industries.

It remained mostly an agrarian region until much later.

The modern canton of Aargau was finally created in 1803. This happened because of the Act of Mediation during the Napoleonic era. The new canton combined three short-lived regions. These were the cantons of Aargau, Baden, and Fricktal. Each of these had existed briefly during the Helvetic Republic.

This reorganization brought the different pieces of the region into one single political unit. The canton celebrated its 200th anniversary in 2003.

Today, Aargau is a mix of historical sites and modern industry. You can see old architecture in the streets of Aarau.

The region has moved from being a disputed borderland to a central part of Switzerland. Its history of division and conquest shaped the way its districts are organized today. The landscape remains defined by the rivers and hills that have seen many different rulers pass through.
