defestival1-6, Exercise 2: Hamburg's port birthday

Model answer (check the details):

The claim: Hamburg's port is celebrated each May on the anniversary of a charter said to have been granted by the emperor Frederick Barbarossa in 1189, giving the city trade privileges on the Elbe.

The problem: historians have shown that the charter is a forgery produced in the 1200s, so the specific date of 1189 is not a real founding date.

Why the festival is still real:
- The event exists today and draws large crowds, whatever the charter's status.
- The festival began in the 1900s (check the first year), so it is a modern civic celebration, not a medieval one.
- Hamburg's port and its trade privileges are real and old, even if the charter cited is not authentic.
- A tradition is defined by people doing it, not by the truth of its origin story.

What it shows: when you test a custom, separate the festival (a fact today), its founding story (which may be false) and the real history behind it (which may be older and different).
