What is the relationship between inflation/deflation and the cross of gold speech?

The "Cross of Gold" speech was given by William Jennings Bryan in 1896 at the Democratic National Convention, where Bryan stated his support for "free silver" to bring prosperity to the nation. Inflation is when the purchase cost of goods and services rise, whereas deflation happens when those prices decrease. The Cross of Gold Speech was believed to bring about inflation for the economy. 

The business cycle is the periodic but irregular up-and-down movement in economic activity, measured by fluctuations in real gross domestic product (gdp) and other macroeconomic variables. a business cycle is typically characterized by four phases—recession, recovery, growth, and decline—that repeat themselves over time. economists note, however, that complete business cycles vary in length. the duration of business cycles can be anywhere from about two to twelve years, with most cycles averaging six years in length. some business analysts use the business cycle model and terminology to study and explain fluctuations in business inventory and other individual elements of corporate operations. but the term "business cycle" is still primarily associated with larger (industry-wide, regional, national, or even international) business trends.
