This is based on the difference between dates; if counted by number of calendar days all the figures would be one greater . (Note that the shortest - reigning and longest - reigning pope lists use numbers of calendar days .) Bismarck's successive tenure as Chancellor of the North German Confederation (1867 - 1871) and of the German Empire (1871 - 1890) is counted as one continuous term; Müller and Marx's double terms are treated as single, continuous tenures . </P> <Table> <Tr> <Th> #in office </Th> <Th> Chancellor </Th> <Th> Time in office </Th> <Th> Rank </Th> </Tr> <Tr> <Td> </Td> <Td> Prince Otto von Bismarck </Td> <Td> 7003840000000000000 ♠ 22 years, 364 days </Td> <Td> </Td> </Tr> <Tr> <Td> </Td> <Td> Count Leo von Caprivi </Td> <Td> 7003168100000000000 ♠ 4 years, 220 days </Td> <Td> 11 </Td> </Tr> <Tr> <Td> </Td> <Td> Prince Chlodwig zu Hohenlohe - Schillingsfürst </Td> <Td> 7003217900000000000 ♠ 5 years, 353 days </Td> <Td> 10 </Td> </Tr> <Tr> <Td> </Td> <Td> Prince Bernhard von Bülow </Td> <Td> 7003319200000000000 ♠ 8 years, 270 days </Td> <Td> 6 </Td> </Tr> <Tr> <Td> 5 </Td> <Td> Theobald von Bethmann - Hollweg </Td> <Td> 7003292100000000000 ♠ 7 years, 364 days </Td> <Td> 8 </Td> </Tr> <Tr> <Td> 6 </Td> <Td> Georg Michaelis </Td> <Td> 7002110000000000000 ♠ 110 days </Td> <Td> 26 </Td> </Tr> <Tr> <Td> 7 </Td> <Td> Count Georg von Hertling </Td> <Td> 7002333000000000000 ♠ 333 days </Td> <Td> 20 </Td> </Tr> <Tr> <Td> 8 </Td> <Td> Prince Maximilian of Baden </Td> <Td> 7001370000000000000 ♠ 37 days </Td> <Td> 30 </Td> </Tr> <Tr> <Td> 9 </Td> <Td> Friedrich Ebert </Td> <Td> 7001960000000000000 ♠ 96 days </Td> <Td> 28 </Td> </Tr> <Tr> <Td> 10 </Td> <Td> Philipp Scheidemann </Td> <Td> 7002127000000000000 ♠ 127 days </Td> <Td> 25 </Td> </Tr> <Tr> <Td> 11 </Td> <Td> Gustav Bauer </Td> <Td> 7002279000000000000 ♠ 279 days </Td> <Td> 22 </Td> </Tr> <Tr> <Td> 12 </Td> <Td> Hermann Müller </Td> <Td> 7002710000000000000 ♠ 1 year, 345 days </Td> <Td> 17 </Td> </Tr> <Tr> <Td> 13 </Td> <Td> Constantin Fehrenbach </Td> <Td> 7002313000000000000 ♠ 313 days </Td> <Td> 21 </Td> </Tr> <Tr> <Td> 14 </Td> <Td> Joseph Wirth </Td> <Td> 7002553000000000000 ♠ 1 year, 188 days </Td> <Td> 18 </Td> </Tr> <Tr> <Td> 15 </Td> <Td> Wilhelm Cuno </Td> <Td> 7002263000000000000 ♠ 263 days </Td> <Td> 23 </Td> </Tr> <Tr> <Td> 16 </Td> <Td> Gustav Stresemann </Td> <Td> 7002109000000000000 ♠ 109 days </Td> <Td> 27 </Td> </Tr> <Tr> <Td> 17 </Td> <Td> Wilhelm Marx </Td> <Td> 7003116800000000000 ♠ 3 years, 73 days </Td> <Td> 13 </Td> </Tr> <Tr> <Td> 18 </Td> <Td> Hans Luther </Td> <Td> 7002482000000000000 ♠ 1 year, 117 days </Td> <Td> 19 </Td> </Tr> <Tr> <Td> 19 </Td> <Td> Heinrich Brüning </Td> <Td> 7002792000000000000 ♠ 2 years, 61 days </Td> <Td> 16 </Td> </Tr> <Tr> <Td> 20 </Td> <Td> Franz von Papen </Td> <Td> 7002169000000000000 ♠ 169 days </Td> <Td> 24 </Td> </Tr> <Tr> <Td> 21 </Td> <Td> Kurt von Schleicher </Td> <Td> 7001560000000000000 ♠ 56 days </Td> <Td> 29 </Td> </Tr> <Tr> <Td> 22 </Td> <Td> Adolf Hitler </Td> <Td> 7003447300000000000 ♠ 12 years, 90 days </Td> <Td> 5 </Td> </Tr> <Tr> <Td> 23 </Td> <Td> Joseph Goebbels </Td> <Td> 7000100000000000000 ♠ 1 day </Td> <Td> 32 </Td> </Tr> <Tr> <Td> 24 </Td> <Td> Lutz Graf Schwerin von Krosigk </Td> <Td> 7001210000000000000 ♠ 21 days </Td> <Td> 31 </Td> </Tr> <Tr> <Td> 25 </Td> <Td> Konrad Adenauer </Td> <Td> 7003514400000000000 ♠ 14 years, 31 days </Td> <Td> </Td> </Tr> <Tr> <Td> 26 </Td> <Td> Ludwig Erhard </Td> <Td> 7003114200000000000 ♠ 3 years, 46 days </Td> <Td> 14 </Td> </Tr> <Tr> <Td> 27 </Td> <Td> Kurt Georg Kiesinger </Td> <Td> 7003105500000000000 ♠ 2 years, 324 days </Td> <Td> 15 </Td> </Tr> <Tr> <Td> 28 </Td> <Td> Willy Brandt </Td> <Td> 7003165900000000000 ♠ 4 years, 198 days </Td> <Td> 12 </Td> </Tr> <Tr> <Td> 29 </Td> <Td> Helmut Schmidt </Td> <Td> 7003306000000000000 ♠ 8 years, 138 days </Td> <Td> 7 </Td> </Tr> <Tr> <Td> 30 </Td> <Td> Helmut Kohl </Td> <Td> 7003587000000000000 ♠ 16 years, 26 days </Td> <Td> </Td> </Tr> <Tr> <Td> 31 </Td> <Td> Gerhard Schröder </Td> <Td> 7003258300000000000 ♠ 7 years, 26 days </Td> <Td> 9 </Td> </Tr> <Tr> <Td> 32 </Td> <Td> Angela Merkel </Td> <Td> 7003464100000000000 ♠ 12 years, 258 days </Td> <Td> </Td> </Tr> </Table> <Tr> <Th> #in office </Th> <Th> Chancellor </Th> <Th> Time in office </Th> <Th> Rank </Th> </Tr>
