I'm not familiar with those. Can you point out a website that has more about them?
Why would the south be offended?
Since every southern state had laws on their books at one time or another prohibiting free blacks from entering the state, and a number had those same prohibitions in their constitution, it's not hard to imagine that they wouldn't want free blacks in areas where they wanted to expand their slavery. Unless you have some information to the contrary?
I'm not aware of a particular website that lists each act, but INS lists the titles of the naturalization acts themselves @ http://www.ins.usdoj.gov/graphics/aboutins/statistics/legishist/index.htm
The Act of March 26, 1790 (1 Stat 103-104), (An Act to establish an uniform Rule of Naturalization), stated that
"any alien, being a free white person, who shall have resided within the limits and under the jurisdiction of the United States for the term of two years, may be admitted to become a citizen thereof ..."
Followed by the Act of January 29, 1795 (1 Stat 414), which continued the practice,
"[A]ny alien, being a free white person, may be admitted to become a citizen of the United States..."
Then continued with the Naturalization Act of 1798 (1 Stat 570) , the Act of April 14, 1802 (2 Stat 153), the Act of May 26, 1824 (4 Stat 36). Even the Militia Act of 1792 limited service to "every free, able-bodied, white male citizen."
It wasn't until the Naturalization Act of July 14, 1870 (16 Stat 254) that officially legalized US citizenship for blacks.
Unless you have some information to the contrary? [that the South wouldn't want free blacks in areas where they wanted to expand slavery]
Do you have documentation where the South specifically requested that free blacks be excluded from the territories? The North also had free blacks, yet the Free Soil policy was one that advocated the territories being free of ALL blacks, not just slaves.
