Alexander Chalmers (1645 – 9 March 1703; Polish: Aleksander Czamer) was a Scottish-born merchant, jurist, and city mayor and councilor active in Poland.
In 1676, King John III Sobieski confirmed the rights of the eight Scottish merchants who served his court, including Chalmers.
[1][2] While deputy mayor, he went into conflict with the Dominican Order, which organized congregation in the city without paying fees.
One person died during the riot, and the aftermath led to long-lasting disagreement between the city and the Catholic Church.
The court organized after the riot, decided in favour of Dominican Order, and removed Chalmers from his position, and barred him from holding public offices for the following three years.
In 1690, the city authorities decided to grant Alexander and his wife, Christina Lang, a piece of land in perpetuity for an annual fee of 20 florins.
