In this ambitious, groundbreaking, and sweeping work, Jonathan Sperber guides readers through six decades of global history, from the end of World War Two to the onset of the new millennium. As Sperber's immersive and propulsive book reveals, the defining quality of these decades involved the rising and unstoppable flow of people, goods, capital, and ideas across boundaries, continents, and oceans, creating prosperity in some parts of the world, destitution in others, increasing a sense of collective responsibility while also reinforcing nationalism and xenophobia. It was an age of transformation in every realm of human existence: from relations with nature to relations between and among nations, superpowers to emerging states; from the forms of production to the foundations of religious faith. These changes took place on an unprecedentedly global scale. The world both developed and contracted. Most of all, it became interconnected.

To make sense of it, Sperber illuminates the central trends and crucial developments across a wide variety of topics, adopting a chronology that divides the era into three distinct periods: the postwar, from 1945 through 1966, which retained many elements of period of world wars; the upheaval of the 1960s and 1970s, when the pillars of the postwar world were undermined; and the two decades at the end of the millennium, when new structures were developed, structures that form the basis of today's world, even as the iconic World Trade Center was reduced by terrorism to rubble. The Age of Interconnection is a clear-eyed portrait of an age of blinding change.
