The primary cause was the federal government’s effort to counteract state policies of racial segregation through civil rights enforcement and legislation , especially in the mid‑1960s.

Quick Scoop

In the 1960s, landmark federal civil rights actions—like enforcing desegregation and protecting voting rights—directly overrode many state laws and practices, shifting real power toward Washington, D.C. This made the federal government the dominant actor on questions of race, equality, and individual rights.

What changed in the 1960s?

  • Major civil rights laws (for example, those passed in 1964–1965) struck down state-level segregation and discriminatory voting systems.
  • Federal courts and federal agencies increasingly stepped in when states refused to protect constitutional rights.
  • This pattern meant that, in practice, states could no longer maintain many of their traditional policies if they conflicted with new federal civil rights standards.

Why this weakened state power

  • States that had relied on segregationist laws saw those laws invalidated or overridden, reducing their control over key policy areas like schools, elections, and public facilities.
  • The federal government’s willingness to use legislation, courts, and enforcement tools to protect civil rights signaled that national authority would prevail when state policies violated individual rights.

Simple one-line answer for class

In the 1960s, state governments lost power mainly because the federal government moved aggressively to defeat state racial segregation and enforce civil rights, expanding federal authority over the states.

TL;DR: The balance tipped toward Washington because federal leaders used civil rights laws and enforcement to overrule segregationist state policies, reducing state governments’ relative power.
