Problem: During the 19th century, the major European powers went to great lengths to maintain a balance of power throughout Europe, resulting in the existence of a complex network of political and military alliances throughout the continent by 1900. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria. When Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany. This agreement failed because Austria-Hungary and Russia could not agree over Balkan policy, leaving Germany and Austria-Hungary in an alliance formed in 1879, called the Dual Alliance. This was seen as a method of countering Russian influence in the Balkans as the Ottoman Empire continued to weaken. This alliance expanded in 1882 to include Italy, in what became the Triple Alliance. Bismarck had especially worked to hold Russia at Germany's side in an effort to avoid a two-front war with France and Russia. When Wilhelm II ascended to the throne as German Emperor , Bismarck was compelled to retire and his system of alliances was gradually de-emphasised. For example, the Kaiser refused, in 1890, to renew the Reinsurance Treaty with Russia. Two years later, the Franco-Russian Alliance was signed to counteract the force of the Triple Alliance. In 1904, Britain signed a series of agreements with France, the Entente Cordiale, and in 1907, Britain and Russia signed the Anglo-Russian Convention. While these agreements did not formally ally Britain with France or Russia, they made British entry into any future conflict involving France or Russia a possibility, and the system of interlocking bilateral agreements became known as the Triple Entente.

Problem: Hoping to rebound from their road loss to the Redskins, the Panthers flew to Lincoln Financial Field for a Monday Night fight with the Philadelphia Eagles. In the scrappy first quarter, Carolina struck first with QB Jake Delhomme completing a 9-yard TD pass to WR Steve Smith for the only score of the period. In the second quarter, the Eagles responded with QB Jeff Garcia completing an 8-yard TD pass to RB Brian Westbrook. Fortunately, the Panthers would regain before the half with Delhomme completing a 1-yard TD pass to the back corner of the endzone, caught by WR Keyshawn Johnson. In the third quarter, Philadelphia struck back with Garcia completing a 30-yard TD pass to WR Donte' Stallworth. Yet again, Carolina regained the lead with Delhomme completing a 35-yard TD screen pass to rookie RB DeAngelo Williams, who rushed well after a shaky first quarter. In the fourth quarter, the Eagles crept closer with kicker David Akers getting a 28-yard field goal. The Panthers responded with kicker John Kasay getting a 45-yard field goal. Philadelphia would respond with Garcia completing a 40-yard TD pass to WR Reggie Brown. Then, things got grim when Delhomme got intercepted by Free Safety Brian Dawkins under pressure in the pocket, which led to Akers kicking a 25-yard field goal. Carolina tried to fight back as they marched deep into Philly territory, but came up short when Delhomme got intercepted again by cornerback Lito Sheppard in almost the same spot where Keyshawn Johnson made the earlier TD completion. Johnson claimed pass interference from Sheppard, but an official review decided this was not the case. With the loss, not only did the Panthers fall to 6-6, but it also marked the 5th time this season the Panthers had the lead going into the fourth quarter and lost. In many Panther's fans minds there was much pass interference and Shepard never had possession anyway.
