Final answer:
The Frankfurt Parliament had differing opinions on who should be included in a unified Germany. They debated between a "smaller German" state excluding Austria and a "greater German" state including Austria. However, the parliament was unable to achieve its goal of unifying the German states.
Step-by-step explanation:
The attitude of the Frankfurt Parliament towards non-Germans was quite complex and varied. The parliament, which was the first popularly elected national assembly in German history, gathered to create a unified state based on the principle of German unity and a liberalized legal order. However, the delegates had differing opinions on who should be included in this unified Germany. There was debate between a "smaller German" state that excluded Austria and a "greater German" state that included Austria and other ethnicities. Ultimately, the Frankfurt Parliament was unable to achieve its goal of unifying the German states and creating a constitution.
