In 2013, Bremgarten was the first municipality in Europe to introduce laws forbidding asylum seekers from visiting certain public places such as libraries, swimming pools, schools and churches.

Bremgarten's population grew rapidly, and it became an important market town with an outstanding Latin school.

Two districts were created: a "high" one for Ober- and Unterlunkhofen, Arni, Islisberg, Jonen, Werd and Huserhof and a "lower" one for the remaining village.

While Bern kept the southwest portion which consisted of Zofingen, Aarburg, Aarau, Lenzburg, and Brugg.

Bremgarten, together with the rest of the Freie Ämter (Mellingen, Muri, Villmergen, and the countship of Baden), were governed as "subject lands" by all or some of the Confederates.

When Bremgarten refused the offer to join the Confederation freely, it became involved in the 1443 Old Zürich War, in which it was besieged and captured.

During the French Revolution, it became for a short time host to Louis-Philippe, who sought refuge from the revolutionaries.

Marshal André Masséna moved into Bremgarten, along with his headquarters, before his troops defeated those of Russia and Austria near Zürich.

During the time of the Helvetic Republic, Bremgarten became part of the short-lived Canton of Baden.

Like everywhere in Europe, the era after World War II marked a vast increase in motorised traffic.

This was a big problem, because all the traffic needed to pass a small wooden bridge in the middle of the old part of the town.

Of the rest of the land, 25.6% is settled (buildings or roads) and the remainder (8.4%) is non-productive (rivers or lakes).

The blazon of the municipal coat of arms is Argent a Lion rampant Gules.

[7] The age distribution, as of 2008[update], in Bremgarten is; 651 children or 10.4% of the population are between 0 and 9 years old and 692 teenagers or 11.1% are between 10 and 19.

[15] The entire village of Bremgarten is designated as part of the Inventory of Swiss Heritage Sites.

[18] From the 2000 census[update], 2,720 or 51.0% were Roman Catholic, while 1,146 or 21.5% belonged to the Swiss Reformed Church.

[12] Bremgarten is famous for its four large markets, which attract tens of thousands of visitors and are important for tourism.

The Old Town Market is held over two days at the end of October and focuses on arts and crafts.

With over 100,000 visitors and more than 300 stalls, it is now the largest Christmas market in Switzerland and has gained international renown.

The following year, the Verein KulturZentrum Bremgarten KuZeB[21] was founded with the aim of creating a small version of the Wohlgroth in Zurich.

KuZeB's cultural programme ranges from concerts of alternative and subculture of international format to readings and political lectures.
