Economic depression

Explanation:

An economic depression is characterized by an aggravated state of recession, that is, a long period of mass unemployment, bankruptcy of companies, low levels of production and investments, etc., always leading to negative consequences for a country's economy.

Based on this, we can conclude that the best for a science fiction story written by a British author in 1898 is economic depression. By that time, England began to lose its power over other countries. This loss of power has led to a decrease in the country's economic power. For this reason, the author could draw inspiration from this weakening economy and write about a society that was facing economic depression.
