The term DACH represents the German-speaking countries of Central Europe: Germany, Austria, and Switzerland. The name is derived from their country codes— D (Deutschland), A (Austria), and CH (Confoederatio Helvetica).

The term DACH entered mainstream business vocabulary in the late 20th century (1980s–1990s), as European markets began integrating more deeply and cross-border trade intensified.

Over time, DACH evolved from a simple abbreviation into a strategic business classification, widely used by global enterprises, consulting firms, and policymakers.
