This chapter provides an introduction and framework to the volume. It provides a historical overview of constitutional thought and highlights the four principles of constitutionalism: rule of law, separation of powers, constituent power, and rights. It demonstrates the ways in which this history and these principles are relevant for global constitutionalism. It argues that a practice-based approach to global constitutionalism provides space for contestation of the traditional liberal history and principles of constitutional thought, highlighting new ways in which this idea can be understood and assessed.

A legal cycle is legislation that takes effect contingently, where contingent factors are ex ante known to fluctuate with some level of predictable regularity. Apart from broad constitutional mandate, lawmakers have historically and suboptimally responded to legal cycles with general and patchwork patterns of legislation involving repeal, amendment, and new enactment. This is true across nearly all domains of codified law. This chapter develops a normative theory of how lawmakers should respond to legal cycles by setting forth the optimal architecture of stabilization rules. Under a general set of conditions, stabilization rules work toward smoothing fluctuations in rulemaking and exert downward pressure on short-term legislative pathologies that result from cognitive bias and interest group politics. The potential of welfare-enhancing stabilization rules is discussed across banking law, budget law, environmental law, health law, national security law, and criminal sentencing.
