What, in addition to economic differences, may have led to the division of Czechoslovakia?

technological development, l difference.

Explanation:

On January 1, 1993, Czechoslovakia split into two independent states, the Czech Republic and Slovakia, in what is now known as the "Velvet divorce" due to its peaceful and negotiated nature. Both countries divided their common "goods" (embassies, military equipment, etc.)

The Czechs and Slovaks were not at the same level of economic and technological development, but the freedom and opportunity found in an independent Czechoslovakia enabled them to make strides toward overcoming these inequalities.
