Arthur James Balfour (1848-1930) was born toward the beginning of Queen Victoria's long reign. At her death in 1901, he was a year away from becoming the first prime minister of the Edwardian era. Inthe quarter century after his entry into political life in the 1870s, Britain experienced material changes and a sense of intensifying human interactions as dramatic to his generation as the forces ofglobalization are today. Aristocrats watched anxiously as gifted boys from the middle classes rose to the top in professional life. Culture wars over male and female behaviours erupted at home, as small wars of empire proliferated overseas. Politicians came to terms with electioneering among the masses and with a boisterous print culture that prefigured the mass media of the next century. The first great era of advanced, international capitalism affected every segment of British and imperial society, including the rarefied domain of Arthur Balfour.

That changes of the magnitude that Balfour's generation faced would demand different skills, career paths or political alignments is not surprising. That they might also result in the creation of different emotional sets and interiorworlds may be more so. Balfour's World provides an intimate history of how Arthur and his friends - George Herbert, 13th Earl of Pembroke; Laura and Margot (later Lady Asquith) Tennant; Mary and George Wyndham - helped to construct a new 'emotional regime' among Britain's political elites at the fin de si�cle. The rich diaries, letters and publications they left allow access both to publicselves and to inner landscapes, and the mix of psychological patterns and cultural assumptions that mediated their responses to the world. As the new century began, the demeanours modelled by habitu�s of Balfour's world would characterize many in the imperial elite, marking them as a clear bridge between the Victorians and the moderns in Britain's twentieth-century political culture.
