Money—not land—became Europe’s key economic driver in the Middle Age

Feudal landholding organized medieval Europe’s economy without relying on slavery

The Medicis of Italy innovated 'bills of exchange,' precursors to checks

At the time, lending money for interest (also known as usury) was banned in much of the Christian world. The enterprising Medicis developed bills of exchange to allow merchants to promise payment without cash or coin (with some discrete means of earning interest woven in). Learn more about how this family laid the foundation for modern banking.

A medievalist explains how romantic love emerged as a cultural concept

Many long-form stories written in English were originally considered "romances," a term derived from the Old French word for "the speech of the people." But changes in medieval culture, triggered by a number of 12th-century church reforms, led to a new interest in what we now consider romantic love, including a new view of marriage as a pursuit of love rather than a transaction. Those new perspectives were then reflected in the period's popular stories, including stories in Chaucer's "Canterbury Tales."

Enlightenment ideals of reason informed the foundation of the Revolution

From the 17th to 19th centuries, an intellectual movement took place in Europe and its colonies that emphasized reason over authority.

The movement caused a paradigm shift in how societies are organized and how people perceive themselves.

Colonial Americans used tobacco, wampum, and land-backed notes to solve a chronic coin shortage

Opium's history traces from religious use to mass-market commercial products

Religious or medical use of opium was present across Europe and Asia as early as 5000 BCE. By the 16th century, humanity had come to see opium as more than medicine: It was a marketable product. This perspective also defines today's relationship with opioids, highly addictive painkillers at the heart of an ongoing drug crisis.

19th-century Americans discovered tipping in Europe
