From 1874, and particularly under Charles Stewart Parnell from 1880, the Irish Parliamentary Party gained prominence. This was firstly through widespread agrarian agitation via the Irish Land League, that won land reforms for tenants in the form of the Irish Land Acts, and secondly through its attempts to achieve Home Rule, via two unsuccessful bills which would have granted Ireland limited national autonomy. These led to "grass-roots" control of national affairs, under the Local Government Act 1898, that had been in the hands of landlord-dominated grand juries of the Protestant Ascendancy.
