In fact, the fall of property taxes began prior to the 1970s. However, it was not until the late 1970s and early 1980s that dramatic changes occurred. One prominent event happened during that time was the massive enactment of TELs. While TELs on local governments can be traced back to the late nineteenth century, the most significant development of the limitations took place in the aftermath of California’s Proposition 13 (of 1978) and Massachusetts’s Proposition 2½ (of 1980), the so-called tax revolts. The change in municipal revenue and the trend of TELs raise the question of whether TELs are one of the major driving forces of the changing municipal revenue structure. Specifically, do TELs reduce municipal general own-source revenue? Do TELs affect municipal reliance on specific sources of revenue? Do the effects of TELs vary among local jurisdictions under different social–economic conditions?
