Aargau is in Switzerland. 


Aargau is a part of Switzerland. It is one of 26 cantons. A canton is a state or region. 

A long time ago, many groups lived here. The Romans lived in the area. They built a big town called Vindonissa. 
The modern canton was made in 1803. It joined three smaller regions together. These were Aargau, Baden, and Fricktal. The capital city is Aarau. Aargau has eleven districts. Some parts of the land used to be farms. Now, many people work in cities. The region has many different towns and hills. It is a very important part of Switzerland today.
Aargau is a special region in Switzerland called a canton. It is one of 26 cantons that make up the Swiss Confederation. 

Many different groups have lived in this land over a long time. As far back as 200 BC, a Celtic tribe called the Helvetians lived here. Later, the Romans occupied the area and built a large settlement. This settlement was named Vindonissa and was located near what is now Brugg. 
In the year 1415, a big change happened when the Swiss Confederacy invaded. They took control of many towns like Aarau, Lenzburg, Brugg, and Zofingen. 

History shows that different parts of the land had different lives. For example, the area known as Unteraargau became very industrial in the late 1700s. 

The Aargau we see today was officially formed in 1803. This happened because of an agreement called the Act of Mediation. 

Aargau is a canton within the Swiss Confederation. A canton is a member state of Switzerland. 

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. 
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. 
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. 

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