A 1948 article was Stone's earliest venture in the quantitative study of the rise of the gentry and decline of the aristocracy along the lines that his mentor R.H. Tawney had suggested in 1941. He concluded there was a major economic crisis for the nobility in the 16th and 17th centuries. Stone's argument was marred by methodological mistakes and he came under heavy attack from Hugh Trevor-Roper and others. Christopher Thompson, for example, showed that the peerage's real income was higher in 1602 than in 1534 and grew substantially by 1641. Many other scholars entered the fray and the so-called storm over the gentry became a central theme of English historiography for some time.
