These were the two quotations from the textbook that I used to illustrate the different assessments various historians might have about the same developments.

In the first quotation, the authors are optimistic because more than 100 years (!!) later, women finally prevailed in their struggle to be allowed to vote. Gouges' head was chopped off in 1793 because of her outspoken position on women's rights.

textbook (Bentley/Ziegler), p. 727:
"Yet Gouges's campaign illustrated the power of the Enlightenment ideals of freedom and equality. Revolutionary leaders stilled her voice, but once they had proclaimed freedom and equality as universal human rights, they were unable to suppress demands to extend them to new constituencies."

In this second quotation, the authors imply that the 1815 congress was not important ("limited success"), although its result lasted for a century.

p. 751
"The efforts of Metternich and the Congress of Vienna to restore the ancien regime had limited success. The European balance of power established at Vienna survived for almost a century, until the outbreak of a general continental and global war in 1914."
