Hackneyed history at best. There certainly were no slaves in 1875.
Brazil did not abolish slavery until 1888. After that they went to a system of wage slaves like me.
I hope you’re just being facetious.
Slaves were in Yucatán Mexico working jute as late as early 1900s. Life was ugly under Porfirio Dias. Well worth a read.
You should be able to find a free PDF of John Turners book Barbarous Mexico.
