This article examines the enduring connections between past and present in world history by analyzing recurrent social mechanisms and evolving practices that enact them. While sociology has traditionally emphasized discontinuities and social change, I argue that some foundational mechanisms persist across time and space, yet they appear under varying practices. Drawing from Charles Tilly’s framework of mechanisms and repertoires of practices, I identify six recurrent mechanisms in world-historical processes: threat attribution, group identification, subordination, affinity bridging, rebellion, and commodification. Then, I provide a broad historical narrative tracing their gradual emergence, beginning with threat attribution in early hominid evolution, group identification in the Upper Paleolithic, and subordination with the transition to agrarian civilizations. During the Axial Age, institutional entrepreneurs and their followers developed affinity bridging and rebellion, which emerged as a reaction to subordination, first manifesting through religious movements and later through secular political practices. I then combine these mechanisms to briefly discuss further historical processes, including the trajectories of Islam and Christianity, the European conquest of Hispanic America, the rise of modern society (where I discuss the intensification of commodification), and the evolving global order following World War II. This perspective views human history as structured by both continuity and change between the past and the present: while mechanisms persist and recur, they are enacted through historically specific and evolving repertoires of practices.
