Final answer:
The commonality between the Indian Removal Act of 1830 and the Naturalization Act of 1906 is that both legislations denied rights based on race, affecting Native Americans and immigrants respectively.
Step-by-step explanation:
The Indian Removal Act of 1830 and the Naturalization Act of 1906 have in common that both denied equal rights and due process to groups of Americans based on race. The Indian Removal Act forcibly relocated Native Americans from their homelands, while the Naturalization Act stipulated more stringent requirements for immigrants seeking citizenship, which often discriminated against non-white individuals. Neither of these acts was immediately overturned by the Supreme Court after they went into effect. Indeed, the struggle for Native American rights continued well into the 20th century, marked by policies like the Indian Citizenship Act of 1924 and the Indian Reorganization Act of 1934, which aimed to address some injustices but still left many issues unresolved.
