Why did the union government introduce an income tax and begin selling government bonds

State and federal inheritance taxes began after 1900, while the states (but not the federal government) began collecting sales taxes in the 1930s. The United States imposed income taxes briefly during the Civil War and the 1890s. In 1913, the 16th Amendment was ratified, permanently legalizing an income tax. Hope this helps :)

the safahids used force when persuasion to convert from being a sunni muslim to embrace shi'ism was not effective. they also persecute shi'ites who have different views from their imposed teachings.
