Query: The German Empire had how many universities?
Context: In the 15th century, twenty-eight new ones were created, with another eighteen added between 1500 and 1625. This pace continued until by the end of the 18th century there were approximately 143 universities in Europe and Eastern Europe, with the highest concentrations in the German Empire (34), Italian countries (26), France (25), and Spain (23) – this was close to a 500% increase over the number of universities toward the end of the Middle Ages. This number does not include the numerous universities that disappeared, or institutions that merged with other universities during this time.
