How did chocolate spread from Spain to other parts of Europe?

Although Spain initially guarded the secret of its chocolate beverage for nearly a century, the consumption of chocolate eventually spread throughout Europe through diplomatic ties, trade, and the establishment of social venues.1

Key milestones in this expansion include:

• Diplomatic Influence: Chocolate gained popularity in France following the marriage of the Spanish princess Maria Theresa to Louis XIV in 1660.1
• Early Adoption: The beverage reached Italy by 1606, where it was used in both savory dishes and early chocolate sweets.12
• Chocolate Houses: In 1657, a Frenchman opened a shop in London selling solid chocolate for beverage preparation. This led to the rise of fashionable chocolate houses across European capitals, which served as social hubs for the wealthy and, in London, as centers for political and gambling activities.13

While the beverage was initially expensive due to high import duties in places like Great Britain, it eventually became more accessible as production methods evolved and costs were reduced.3
