Page "Deutschlandlied" Paragraph 10

After the March Revolution of 1848, the German Confederation handed over its authority to the Frankfurt Parliament, and Eastern Prussia joined the Confederation.

For a short period in the late 1840s, Germany was united with Hoffman's borders, with a democratic constitution in the make, and with the black-red-gold flag to represent it.

The two big monarchies put an end to this period of national unification, and waged the Austro-Prussian War against each other.
