When states gave up some of their power to the federal government, which of the following did they receive in return?

When states gave up some of their power to the federal government, they received several things in return, including:

1. Protection: States received protection from external threats, as the federal government was responsible for national defense and security.

2. Economic stability: The federal government's ability to regulate trade, commerce, and currency provided states with economic stability and uniformity across the country.

3. National infrastructure: States received federal funding for the development of national infrastructure, including roads, rails, and ports, which facilitated interstate commerce.

4. Representation: States gained representation at the federal level through the bicameral Congress, giving them a voice and influence in national decisions.

5. Legal framework: States received a unified legal framework through the federal judiciary system, ensuring consistent interpretation and application of laws.

6. Centralized services: The federal government provided centralized services, such as postal services, which benefited all states.

It's important to note that the nature and extent of the powers transferred to the federal government varied over time and were outlined in the U.S. Constitution. Additionally, the balance of power between the federal government and states has been an ongoing and debated topic throughout American history.
